I completely missed the introduction you linked. That's _amazing_.
As a non-designer, I've had a few situations where I've wanted to use a minimal icon pack but it's missing the one or two icons I would need. I'm not opposed to putting something together myself (Inkscape, etc aren't that scary) but I always end up visually inconsistent. I just never know what to look for
But this? I can totally make an icon that fits this visual language. Even better since I can take an icon I like from another OSS icon pack and just make it fit. Even better than I can contribute back if I wanted to
