suggestion for todo states with swipe

[pvinis]

hello.
i thought it would be cool to do this:
lets say we have a list item, that is TODO. then i can swipe to the right, and it will go to NEXT. then i can swipe again and it will go to DONE. swiping left will put it back to NEXT.

does that sound interesting? it would be even better if it can get the "next" state the same way org-mode gets the next state, either by the top file todo tags, or custom ways.
