Few thoughts:
* Where can we give feedback other than here? Github repo or support site?
* Request: For those of us with large monitors, being able to change all fonts (not just diff) would be huge. (On OS X for reference.) Been a gripe of mine with SourceTree for a while.
* Potential bug: I changed the default folder for repositories, but it doesn't seem to have changed the list of repositories sourced from the default folder, when I did that.
* Request: add a 'Done' button to right side of the commit dialog. Having to press 'Cancel' after making commits feels like you're undoing changes.
