3+ trees/panes

Hello,
I was reading some older posts about having 3+ trees/panes and the suggestion offered was to use Layouts to achieve it.
As I would really like this feature too, I just gave it a try.

My problem is that I really need to ALT+TAB a lot to different applications while using DO. With the new Layout it's almost impossible to do that as one of the 2 instances of DO aren't sent to front/back at the same time.
Is there any way to link the 2 instances of DO somehow? so that they are always on the same level and next to each other when I ALT-TAB to DO?

Thanks :slight_smile:

A script using the OnActivateLister event might be able to do something along those lines.
