What I don't fully understand is why you want to open the 3 files in your IDE. Just to find the files easier where you were working on the task and now have to continue, or to undo some irrelevant changes? What if you deleted a few files in your branch - should they also be shown for editing (or just those available in the working copy)? Do you need to see the changes made in your branch or just the files (that were changed in your branch) in its current working tree state?

In your opinion what should be searched for - file names (of open repositories), repository names/paths, branches, tags, commit IDs (could be a long list when just having typed 1 char)?
