Launching Tue Oct 20: try kosa8 early and tell me what breaks

We go live on Product Hunt on Tuesday. Before then, I'd love a few people to put the https://kosa8.com/ through its paces:

Post your rough edges, confusing docs or "why doesn't it do X" here. I'll fix what I can before launch and credit you in the changelog. I'll also be here all day on the 20th for questions.
