hello i had an idea which can improve many features of C2. to make the tree for behaviour settings more complicated, (pin and solid could have at least had active at start) in a tree it is very easy to navigate. some games only need the single line of gravity in them with many hundreds of objects, so it would be better to disable some features of a behaviours. in pin, choose which object to be pinned to. solid, (solid for solid/other behaviors).
