When trying to drag a repository to another folder or to another place in the current folder (e.g. when trying to move a repository from the bottom of the list to the top) the reorder fails.

1) You cannot drag beyond what is currently displayed on the top of the screen. In the previous version sourcetree used to scroll the list so you could drag to the top, now it just does nothing, or suggests that you want to drop it in the top level (i.e. at the bottom of the list)

2) If the drag fails sourcetree puts the repository at the bottom in the global folder

So now the only way to have repositories in a sensible order is to change the backend XM
