The section below that is outlined in red has gone missing from my SourceTree window. The list of files now occupies the space that the missing portion used to fill. The hunks on the right still appear.
Also, the missing section does appear in the Search View.
I've searched high and low for a toggle or some kind of handle to drag from the edge of the pane. I'm at a loss and any help is appreciated.
Note: I'm using the Mac client.
