When I look at the GUI apps for Git at https://www.git-scm.com/downloads/guis , I can see for the picture of GitExtensions that the commit details subwindow is to the right of the commit history subwindow.

But I can't do that with my copy of GitExtensions that I just installed today. I found no way to change the layout, with the only layout being the commit history subwindow at the top and all the detail subwindows at the bottom.

How can I change the layout like in that picture in the Git GUI page (and do even more changes if possible!) so I can better use the massively underused screen space on my big wide monitor?
