More hotkeys in event sheet

  • What: Being able to expand and collapse event groups by pressing ← and → when they are selected.

  • Why: I have problems trying to click the vanilla expand/collapse arrow because it lags too much when too many event groups are expanded. (Its my hardware’s problem, not gdevelop’s)

I hope this get added in both the website and desktop application, as it is a simple thing and doesn’t require 100 lines of code.

Edit: Removed the second suggestion because it already exists.
