[PD] pixeltango nice feature not tested

[patrick]

hi ben,
welcome back :)

i'm really ok with "From the user perspective" but not sure to understand
all the technical stuff related to this idea. frank, what do you think about
that? i would like to help in any way. i think it would be a great thing for
pd to have this kind of state-saving and mapping (it's a little bit the
basic of an audio software).
