Hey,
is it possible that I can open a plugin via a script?
Example: I have two plugins.
Plugin A & Plugin B.
I would like to be able to open and close plugin B via a button in plugin A.
Is this possible?
Thanks to you for a short info 
Best regards from Germany.
AFAIK the only way is if you know that other plugin name in menu. Find its command ID (should be negative) and then execute menu command.
Oh yes, thank you very much, that was the right idea.
Works right away :)!
Communication between plugins seems to be configurable in manifest v5.
