Hello,Is it possible from a Smart Client plugin to detect that the client has entered/leaved the Setup-mode?Best regards,Mathias

Yes. There is a “WorkSpaceStateChangedIndication” that you can use.

In order to see this for yourself I recommend that you explore the Message Tester tool plugin sample:
