Pro Extremely easy to use
A lot of care has gone into trying to make GitKraken as easy and intuitive as possible and it show. Every action is quick and painless with no more user interaction than necessary. For example, switching to another branch is as easy as a double-click on the sidebar.
Pro Beautiful user interface
It's modern and beautiful, it looks clean and refined.
It's simple: the most used features (pull, push, branch, stash, commit) are accessible in one click, and are the only buttons. The other features aren't in complicated menus nor in hundreds of buttons, but rather displayed when you right-click on something.
It gives more space to the commits, i.e. the most important things. In fact, you can collapse or reduce the other menus/windows.
It displays the current path (project, branch) on an horizontal (clickable) bar at the top. It's just a matter of taste but I prefer this to the traditional "tree" view.
It has undo and redo buttons on the main window.
It supports some drag-and-drop gestures (for example: drag-and-droping the local branch to the remote one pushes it).
Con Has memory-related issues
Like most Electron apps, GitKraken has some memory-related issues. For starter, it requires more memory for an action than an equivalent non-Electron application. Although this should not be a problem most of the time for people who use machines with lots of RAM (after all, RAM is pretty cheap nowadays), it can have some issues when opening large repositories and there have been cases where GitKraken failed to open very large repositories or started lagging once they were opened.
