being able to click a commit and see the files and changes in question is awesome, however for any files where there is an add instead of modify, double-clicking on the file name does nothing. Would be nice to be able to view the added files when clicking down the "affected paths" list.
You can open an added file from "affected paths" using the contextual menu "Open" action. I added an issue on our internal issue tracker to implement also "Compare" action for the added files from the "affected paths".
We implemented a Compare action on the files displayed as Added in the Affected Paths area of the History view. It will be available in version 3.2 which will be released in a couple of days.
