I'm using SourceTree 1.9.4.1 in Flat | Split View Staging mode.
When I drag a file from unstaged to staged, the selection moves to the next unstaged file, instead of sticking with the selected file I just dragged. The experience is jarring, as generally I am reviewing changes in the diff pane, deciding what to drag up. As soon as I drag, the diff pane shows a different file making me feel like I just operated on the wrong file.
I request that the selected file remain selected after dragging from one area to another.
