well done on building this. Sometimes making is its own reward.

Some feedback:

I had no idea what it did and the opening screen about loading config etc was confusing. I would have preferred like a tour with tooltips instead. Though once you get into it and play you soon figure out what it does.

As a fellow maker - I generally have really basic UI and leave menu items visible and learn from these forums what to do with them. So I suggest expanding your menu and have it always available. (like the menu animation though, could be a little faster).

What problem were you trying to fix? Did you try something like Trello.com before you decided to build this? It's cool if you built it just because.
