I will be free to add one more suggestion, easiest way for me to describe what's bugging me is present it as use case:
I am using "Decompose into work" window and actually working on tasks
from 2 or 3 stories that are in progress, but since current work is some
big refactoring in early stage often I must add new stories just to
document some problem that I saw in the code, or some other component or
class needs refactoring or interface change, I must pause work on
current component or class and fix that broken one. And that case can
go further as I find more broken things. "Decompose into work" window
is great help in this case, really great, but I have to change stories
and then I have to open stories window and edit it there.
That is the problem, for me this would be more than enough to fix this:
1. Stories grid should be editable
2. Text of the story shown in right upper corner should be editable
3. It would be nice when all task inside story is Done, then automatically set story status to Done
here is the screenshot
btw. all this is not such big deal, but that would make work with "Decompose into work" window much faster.
