See [touch] in droidparty abstractions which is built using data structures.. I've been working with it for a while.

Hi list,

what's the current recommendation for a simple x-y Pd GUI controller 
type of thing? Like a slider but horizontal and vertical.
There are probably a few externals providing this, which one is the 
best/most compatible/future proof?
In vanilla this can be emulated with an object reporting its position on 
a canvas, but to use it one must change to the edit mode which is kind 
of counter-intuitive.

Anything I'm missing?
