Revision history on certain file
I love that you can see the history of commits for a specific file by right clicking on the file pane (revision details and commit views) and selecting "file history".
The problem I have with it is you have to select one of the files listed there. There is no way to get that history on a file not listed. (at least that I know) To do that you have to know what one of those revision is so you can have that list of files in the pane. That is not always easy/quick to do.
Proposed solution: allow a right click on the blank area in that same pane bring up a selection window of all the files tracked in the repository. This could be a nice time saver.
