This hits a lot of points that I've been looking for in an app/service. So much so that I was ready to sign up for the paid plan after trying this out for a couples minute, because I'm sure I'd use it enough to be worth it. But I didn't realize the three-levels limitation, and that prevents this from being useful enough to me to start using it.
I'd love to check it out again when you do add infinite nesting.
