I have 3 playbackpages. But if I want to scroll trough the pages, I always have an empty page extra. This is unnecessary I think. I can’t delete the empty page.

Thats just in order to be able to toggle to a new page (the one after last) for show programming. Otherwise you would have to explicitly select a new page from the pages pool and many might potentially never get past 1 page
Agree, but in my case, I need to scroll trough an empty page, which is not useful.
Same issue is in the virtual executors,

We will keep this behavior for the time being.
