It makes sense that one might want to click "TODO" or "DONE" without toggling state: you might want to change the text.
But why does clicking the checkbox (- [ ]) not toggle the X? There isn't a valid state for the checkbox other than the X.
* TODO
- [ ] Item
- [ ] Item
Maybe clicking the brackets should toggle too.
I suppose sometimes you may click with the intention to change the indentation, but they can click elsewhere for that.
This seems unnecessarily insufferable.
