Essentials has a limit of 12 and shapes, elements and lines a limit of 50 downloaded scenes. I really like browsing the discover tab and honestly this “library” of user curated scenes is a big selling point. However, the limits add a lot of maintenance to trying out new scenes. What I do now is preview on my lights to save the hassle of making a decision which to delete. This could all be solved with a bookmark or shortlist button. Bookmark those you like the look of and compare at leisure.
