a possible pro-tip/what i do: organizing your library with categories matching protondb status.

I've categorized every game i own by either borked, bronze, gold, native, platinum, or uncategorized for games not reviewed yet. Any new game I even think about getting i check protondb first. (Though now I try not to buy from steam and just go to DRM-free stores like GOG and Epic through Heroic.)

This way you have a general idea of which games might give you trouble when you go to try to play them, and how much tinkering you might have to get into.

You can also then target just uncategorized games if you wanna contribute to protondb with your own experiences and observations.
