This is a silly, not important thing that would easily be backburnered, but playable lutes/instruments? Could they be a thing?
Why playable instruments? Because sometimes we grow bored of the same songs for the lute emote. Because it'd be funny and creative. Rper's definitely would love it. You could create songs, and thus do community event concerts. You could kind of create a band. People would make videos of themselves.
I don't imagine it'd be too hard to program. Have some normally unassigned hotkeys be the buttons. The numberpad would be great for this. I'm imagining something like the zelda Ocarina, where there's only a few buttons. Maybe change the pitch with the mouse. Nothing overly detailed, but still fun.
Maybe yeah?
