Hi,

if I understand the context concept of Mylyn correctly, for every resource an interest is computed
and every resource which interest is above a threshold is displayed. I think this can be seen in the
Context pane of a task.

Moving the slider in the context pane shows more or less task, but does not influence the display in
the Package explorer. Does it make sense to define different thresholds (two would be OK in the
beginning) which are used in the package explorer display and could be switched easily?

In this way, you could widen your focus to move your attention to different parts of your context.

Are there any plans / RFEs to implement such a feature. Just supplying different configurable focus
thresholds seems to be a rather simple implementation.

Cheers, Jörg

In version 0.2. Mylyn used to expose exactly such a slider Package
Explorer view. The problem is that it made the UI overly complicated.
My current sense is that the best approach would be to automate the most
common use case via the following:

178891: provide adaptive interest filter to prevent scroll bar in
navigator views

Agreed. A slider is far too difficult to handle. I would slightly adapt the Mylyn button to
have (at least) one more state: No filtering - Wide filtering - Narrow filtering. Pressing
the button cycles through the modes, a drop down box allows to select it explicitely.

Actually, the above use case is some sort of opposite to the one of my colleagues:

They touch a lot of different files during their work in a task context, and after they have focused
one a specific sub-set, they want to go back to the wider context with more files.

IMHO, the natural way to accomplish this without several interest thresholds would be to use
sub-task which inherit their initial context from the parent task.

So an alternative approach would be to support sub-tasks between different repositories. Esp. it
would be great if I could attach local tasks as sub-tasks to repository tasks.

Would be great if you have some ideas how we could progress here.

Thanks, Jörg

Jörg,

Your suggestion of supporting this by having subtasks inherit the parent
task's context is a really interesting one. We brainstormed this a
while back but have not picked it up yet. In my PhD thesis I called
these "cascading contexts". I would really like to explore this
further, so please file a new bug outlining what you've suggested and
post a link to this thread. Before filing the new bug please take a
look at the following bug, in particular the description and comment#2.

137543: support displaying task relationships and dependencies, such as
subtasks
