A SmartGit extension that integrates with the two most common Linux File Managers (Nautilus & Thunar) would be incredibly useful and beneficial to your company. You and GitKraken are the two top dogs recommended under Linux. Stay the leader and add this feature because no other Linux Git GUI competitor has this. Note: Under Windows there are many other options and most offer this functionality; that could be why you guys don't rank here. Sorry, to be harsh, but take it as tough love!
