is it possible that i scroll down separately on the right and left side while only the side (the project in my case) i scroll on, is moving down?
hey, no thats not possible with built in RM tools.
You can only have them move down/up in different speeds while scrolling the page.
In general this would be possible if your two panels are nested in their own div containers on which your would then enable scrolling. Allthough this might be possible with custom code I wouldn´t recommend because it would be a bit of a hackaround and would be not easy.
