After selecting a commit, say you go to the Files->Tree view and you expand directory upon directory and navigate your way to a particular file. When you click on it, you get this awesome blame view of that file at that moment in the commit history.
Now you want to see that file at a different point in time, so you select another commit. Instantly the Tree view collapses back up. You now have to go and navigate to that file again, potentially clicking subdirectory upon subdirectory.
Why is this? Am I missing something? Is there a better way to navigate the versions of a file over time?
