Hi!
It would be very nice if we have the ability to create some intelligence / parametric functions in our custom panel objects.
Lets say I build a special doorpanel in GDL and add some parameters, and maybe add an userinterface.
I open the doorobject, choose my doorpanel, then the parameters I have use shows up at the bottom of the parameters for the door. And my userinterface shows upp as a new button on the "Door leaf Type" page.
