BTW, you can turn off the launch bar in the preference if you don’t like it. It’s in the “Launch Bar” preference page.

BTW, the buttons keep shrinking so we keep adjusting. They’re a lot smaller than the BB10 days. And I’m happy to adjust things, but as an every day user of it, I think it’s hit the sweet spot.
Also the document Sergey references is 8 years old. Sorry, was off by two years. The UI world has changed a lot since 2007 as UX people finally have influence on the UIs we are building.
The Launch Bar was designed by professional UX designers trying to meet the needs of new users to make Eclipse less overwhelming with the mass of tiny tool bar buttons we throw at them. I understand that most of us are advanced users and are used to the mess and some even like it, but hopefully there are way more beginner users since that’s how we grow the community. Please have them in mind when discussing these issues.
Also, please hold judgement until you’ve tried it. Check out the Arduino video I’ve posted and I’ll post one for Qt once we get it more full featured. The workflows are beautiful and will really help bring new users into Eclipse. And as an advanced user, I can’t live without it, same with others I know who’ve used it extensively.
At any rate, the Launch Bar is intended to be optional. Though how you set the active target for a given launch configuration will still need some UI for launch configurations that need it.
And I’ll make adjustments to the architecture as the need arises. We’re still early days. What I won’t compromise on is tying builds to the things you are trying to launch on. The workflows are just too good when you do that.

I have to say I've heard the opposite feedback. When I was at BlackBerry, we only had one team member who liked launch bar and he liked it for the workflow benefits, not the giant toolbar buttons. The rest of the team disliked the giant buttons so much they went to elaborate lengths to eliminate the launch bar in order to regain the screen space. My team at Google is much smaller, but we all dislike the big buttons.
I guess we have contradictory anecdotes... so perhaps we shouldn't rely on anecdote.
Maybe you're right and the toolbar buttons in Eclipse are uselessly small. If that's the case, we should update the UI guidelines and make an effort to change all the buttons in Eclipse, not just one toolbar... and before doing such a drastic change, we should make an effort to gather some kind of data (stronger than anecdote) to support the decision.
Until that happens, all toolbars need to follow the UI guidelines. The Eclipse UI is already in a poor state, but if each developer ignores the guidelines they don't like, that makes the UI inconsistent and even worse.

I think they are both fundamental. You have heard of Build for Launch, no?
In case of build for launch the is no dependency of the build subsystem on run/debug. Instead run/debug depends on the build subsystem. By introducing a dependency that is going the other way you are breaking this design and getting dangerously close to creating circular references between build and run/debug subsystems.
Except that it doesn’t create a circular dependency. Feel free to look at the code on master where the Qt plug-ins are now using the new build system. I’m pretty happy with how it turned out and how easy it is to switch between building and launching on my local machine and my QNX board.
It doesn't create a circular dependency because of a very good separation between the build API and build semantics in core.resources. It would otherwise.Having the toolchains know about the launch targets they build for has been a huge advantage in the new build system workflows. It’ll even be more interesting when the toolchains tell debug what debugger to use for a given launch target.
Launch targets is not the only thing that can be built. Consider for a example a shared library, which cannot be launched but can be built. The notion of build in Eclipse is even more flexible and supports code generation and other things.
Yes you build shared libraries, but usually you intend to run them somewhere. The idea is to base what you build on where you intend to run them. I’m still working on the mechanism for that. But likely I’d check the project dependencies and look for the most likely target you’re going to run the library on in the future. Or the user could pick the toolchain manually. We’ll see what provides the best workflow.
Once I get the concept of Launch Target into the Platform post Neon, this conversation wouldn’t be necessary anyway. But, for now, it’s in the launch bar core plug-in.
This is not acceptable. Lauch bar is ugly, violates Eclipse UI guidelines and is shown by default if the corresponding plugins are installed. I understand that you need a place to put interfaces that are used by both, build and launch, but the launchbar plugin is not a right place for them. To preserve the principles of the existing Platform design, these new interfaces have to go into core.resources or another plugin associated with build, not run/debug. If you are concerned with putting immature API into the platform, you can probably avoid that by putting the new interfaces into privately exported packages until they mature.
I appreciate your opinion. And you’re not alone. But you’re also in a pretty small minority. I’ve had a huge amount of praise for the Launch Bar and the simplification of workflows it provides. We can play with the look and feel. But I find Eclipse’s tool bar buttons useless so don’t want to make the launch bar equally useless. And, if you have a pointer to the Eclipse UI guidelines that it’s violating that would be helpful.See "Toolbar, Toolbar Wizard, and Local Toolbar" section in https://wiki.eclipse.org/User_Interface_Guidelines#Icon_Size_.26_Placement for the size of icons. The top and bottom margins of the launch bar don't conform to org.eclipse.jface.layout.LayoutConstants.
I’ve yet to find such a document written in the last decade at least. I can easily make the claim that the current Eclipse UI is hurting us competitively with more "modern looking” IDEs.
But that’s independent of the launch target issue. My intention is to move the launch target classes to the debug.core plug-in. If there was a launch plug-in, I’d move it there since it’s not related to debug anyway, other than debug is a mode supported by the launch system. These classes are actually below the launch bar proper in architecture today ready to be pushed down once I get it up to Platform standards. Again, feel free to take a look at the code.
Would you consider putting the interfaces, which the build has to be aware of, into core.resources? The interfaces would then be considered a part of the build rather than run/debug. Even if the interfaces are not stable yet, they can be put in a package exported with x-friends. This can be done for Neon.
It doesn't make sense that because of the structure of plugin dependencies the Launch Bar gets forced on the CDT users who have no interest in it. Such users, including myself, have to explicitly hide the Launch Bar in every workspace they use. Will this be fixed after 4.6M4?
Not sure what you mean by the target platform definition. The launch bar is in there. Builds are working fine for CDT 9/Neon.
I was seeing compilation errors until I installed Launch Bar. This shouldn't be required since the target platform definition is supposed to take care of that.
You do have this in your cdt-e4.6.target file no?
<location includeAllPlatforms="false" includeConfigurePhase="false" includeMode="planner" includeSource="true" type="InstallableUnit">
<unit id="org.eclipse.launchbar.feature.group" version="0.0.0"/>
<repository location="https://hudson.eclipse.org/cdt/job/launchbar-master/lastSuccessfulBuild/artifact/repo/target/repository/"/>
</location>
The above piece was in cdt-e4.6.target but the build errors didn't go away even after reloading of the target platform definition. It is possible that the Eclipse restart after installing the launch bar also cleaned the whatever PDE cache that got stale.

It doesn't make sense that build.core depends on launchbar. Build is more fundamental than launchbar and should not depend on it. If the dependency were legitimate, it would have to be reflected in the target platform definition.

You get get the Neon launch bar by pointing p2 here:
