Yeah, it's not perfect. I've noticed that when making a task list/checkbox note that you can't delete the line. Sure you can go and edit the contents of that line, but even if you delete all text, the line with a checkbox remains. Kind of annoying, particularly when I accidentally create another checkbox and have nothing to put in it. it's just an empty line and checkbox sitting there mocking me. You can still mark it complete of course, but it kinda makes my eye twitch. :)
