My main use has been as a toDo list. I use it in a pretty basic fashion. Just am outline, I use icons to tick off things that are done. I'd like to be able to do that quicker.
At the moment I select a node, click the suitcase, click plus, type in icon in the first field and check-square in the second. Then click save. I would really like a checkbox on the left to click. I guess the problem with that is lots of folk would like a different icons there doing different things.
