Minor Description
The current toolbar (retrieve/store/revert) doesn't provide any feedback on its underlying functionality. For example, the store/revert buttons only need to be enabled in case the repository is actually modified. And: when retrieving/reverting local changes, it would be nice to have a question that allows the user to cancel the action.
Attached is a patch that solves this issue, making the UI a bit more friendlier to the average user.
