I use Overwatch even though I believe I've been told that it will not ever be updated because it was abandoned or something, but it works for me. I would miss out on a few batches if it weren't for Overwatch. If one requester posts too much/posts a not so great batch and the sound starts to annoy me, I'll just click that requesters name until it turns red, which turns off the notifications for that one requester.
Also, if you ever go to delete cookies or cache, Overwatch will be wiped clear, so be sure to back it up.
