Don't know if I want to invest (both financially and mentally) into a new tool. We have Sketch, that's already pretty awesome, and now we have Figma, that has the material to be even "awesomer", so, don't know ... but Subform looks great, that's to admit.

Another tool! I think this looks amazing (not the interface itself. That looks horrid). Stateful components. Proper constraints. 100k needed though :/
