Alice Averlong🏳️⚧️as someone who is running an emulator approximately 90% of the time she's on the computer:
86box's "Open Screenshots Folder" menu option should be MANDATORY for emulators
Plan A to Y@foone adding "Open Save Directory" and "Open Default ROM/ISO/etc Directory" to that list of demands too.
I hate having to dig through settings to find where it saves things, and sometimes they don't even bother listing so they just expect you to know that "Documents/[appname]" or "Pictures/Captures" or whatever is where it dumps everything.
