Is there any list of builtin variables available? More specifically, I need to use a variable in bindings which provides the current width of the selected item. 

From there I can use margins/borders to divide up the box as a proportion. 

Help appreciated :-)

Is there a way to have folders close when locking the phone?

This is great, but I have a question.

I understand that you can close any folder or swipe menu by tapping in an empty space (as set up in gestures). However there is a noticeable delay, which I believe is down to the software waiting for a double tap.

All the double tap gestures are unset, is there something else I need to do to get rid of the delay?
