Sometimes when I open an event sheet, all of the events are open! This is bad, because it means I now need to close/collapse all events (yet again!) which is a bad use of time as it makes for a cluttered and messy viewing experience, and makes it harder to get where I want to go in the sheet if I have to scroll past every event line.
There is an option to "collapse all groups", but no option to "collapse all events". Events are able to open and close like Groups, so it would be cool if we could extend this feature to events!
