My top two ended up being measured templates and placeable items. The former because of how valuable I think it is to have spell auras automatically appear (without having to make a macro using Token Auras). The latter was because I often want to put items on the map for players, but have to make a journal container for them, which is decently annoying.

I also threw terrain and cover in there, because it's a little annoying to determine, and I'm starting to play more PF2e, and that's a really cool aspect of that system.

Curious to hear about others' use cases and priorities, or what workarounds they use for the issues I mentioned above.
