You’re looking at the wrong thing - what you are organizing are PLE presets whereas what I’m talking about is the list of Macros mirrored from Key Commands
This is a similar Problem to the Quantisation Presets. I’ve quite a lot of them so I can’t see them all on the List. In conjunction with the mouse-wheel bug a nightmare at the moment.
Cubase needs a folder system to organize this long lists - maybe in the media bay?
Your problem is very similar - that’s the reason I pointed this out once again on your topic
There was a “hotfix” in 10.0.x which let us scroll the list - not the best solution but better than the actual dropdown…
