That would be awesome. I literally have thousands of sound files, and I use Windows search feature in a root folder to find something. Like the other day I was looking for a good slide and wall slide sound, so I was just typing terms in to try and find something in all the files I have. It does pick up folder names, which helps. Sadly I didn't find anything great.
Excellent! If I can be a bit more specific, it would be good to have something short and loopable because the problem I've encountered is that when I do find like a gravel slide or something, it's for a specific duration which means you have to tie your animation and slide/wall slide length to that sound, or lety it cut off (I chose the latter).
