Apart from notifications, I just listen to the whole Che not to miss my team components issues.
My main issue with GitHub is running sprints there?
I tried to use Github projects and it works till our components got issues in different places.
Then we got issues in Jira WebTerminalOperator, and it's odd to say how handy GitHub project was for it.
Eventually, I returned back to the issue for the sprint which looks pretty good but it's manual work.
I have to assign collect issues as well, as well as setting milestones for each of them.
Then sometimes it happens that somebody forgot to add an unplanned issue to the sprint
and mainly because it's not just one action, you need to find the current sprint issue, copy the issue title, URL and
modify the sprint issue description.
Maybe Zenhub could help me, but as far as I remember, it's a single repo as well.
And it would be not transparent to the community, that a browser extension is needed to get the actual picture.
I would give a try Jira for that.
