Yep that's on my todo for the next major release. Also hoping to let people group together multiple icon sets and download them all at once.
Tbh, there's a part of me that really doesn't want to try and productize it. I really love the idea of building an icon service that pulls in as many developers/designers as possible. OS has been a huge part of my career, and being able to give back can feel pretty fulfilling on those down-days.
