I don't normally comment on these things, but I gave it a quick shot for a project I'm working on (fairly generic dashboard-style prompt, but that's fine).
I'm actually pretty impressed. A couple things though:
1. It took a _while_ to give me anything. Not sure if that's related to load, but it was ~17 files, and probably took 5+ minutes. It was not clear what was going on in that time, or what would happen if I left it. I literally left my machine to go something else before coming back.
2. I really hate saying this, but your pricing is probably way too low, especially at the "pro" level from your pricing page. When stepping into team-based config management and pre-sets, you're leaving a ton of money on the table without enterprise-style custom value-based pricing. If you were asking me, I would recommend moving the team based features (shared presets, custom access control, etc) into an "enterprise" level above pro).
I'm not going to comment on any sort of "correctness" as far as any complex UX behaviours or workflows; I'm only considering this from a mockup/design/demo-of-new-ideas perspective.
