I am working on a new extension called save state; The goal is saving all object state on the frame like;
Position x,y size x,y angle ... then Load button restore saved state...
After some test all working well , the saved file use internal storage and can only readable by your application no need permission.
Trying to include save integer and string variables of each objects variables. Maybe include each object (Flags are binary) on off on on on on = 47
Be patient ;
