Ok, bus as is the user list and not devel, introduced in case anyone was interested. ;)

Not completely dynamic.. After completing write the controls the idea is just change the list of properties of the controls placed on the form. (Not writing a single line of code more after design forms)

I do not want to limit the ports, but to start i will take into account.

Would be ideal, but I do not see how. Justly my idea was to add a property representing the instance name, and get the instance itself from that. http://gambaswiki.org/wiki/comp/gb/class/instance seems ideal but not work here..

I will investigate this option..
