In the past week I tried the 0.9.x version of this app and I love it. But I still use my paper planner a lot, with its gtd project / next actions lists and its ‘notetaking feature’, which even allows me to create mindmaps (fiddle-proof).

Switching between paper and computer is a bit counter-intuitive, but confusion can be kept under control:

I only use taskpaper for projects and next actions that I have to do at my computer or my desk - I found that everything else, especially project lists, ‘errands’ and ‘waiting for’-tasks, is easier to review in paper. When a project or task is related to an item in taskpaper, I mark it in the paper planner with a rectangle. In taskplanner, items that relate to paper planning can be marked as well, with a tag like @calendar. Works great so far!
