I'm not sure where to post suggestion, feature, improvements, etc...
This is just a small suggestion for the Drag&Drop behaviour:
Possibility to change axes in runtime
I've encountered a few times the need to limit the movement on a particular axis on runtime. I know I can mimic the behaviour with events but Drag&Drop does a better job with multitouch.
So basically I would add a new action:
Set axes with a combobox with three options Both; Horizontal; Vertical.
There's really not that much code to add since it's practically programmed.
