That's really cool! Thank you! It'll help heaps with voice acting because of the number of file you need to manage. Being able to put them in folders is a massive benefit.

Yeah, voice acting IN PARTICULAR struck me as the most likely use case for this in sound effects, and I have another plugin that's all about voice acting, too. Soundtrack Layering also synergizes nicely with this.
But it's just a handy thing to have in general that just never crossed my mind until you brought it up.
