I manage a lot of repositories in SourceTree which makes it necessary to organize them in subfolders. When moving a repository to another location via drag-and-drop, it immediately opens all folders "on the way" to the new location. This is an issue because this means I have to close all of them again manually. My suggestion:

• implement a "collapse / expand all folders" feature for the context menu
• make sure drag-and-drop only opens folders when you've hovered over them for a short amount of time (rather than immediately)
