I've never really understood why you need to either undock the synth rack or dock it in the multidock in order to access the on/off buttons. Seems to me that if space is an issue, the synth name could be truncated and no need to hide the buttons. 

IDK, maybe they thought it was enough to expose the on/off function in the Synth tab menu and change the appearance of the strip in the synth rack.

It seems inconsistent to me. I can't think of any logical reason why they'd want to change the appearance of the synth rack when the browser is docked. They do a pretty good job of making room for the button when the browser is undocked. And you can adjust the width of the browser whether its docked or undocked. Inconsistency like this just contributes to a sense of confusion, especially for newbies. 

And for the record, I am now aware that you can toggle the synths on and off via the synth tab menu. Still, I'd rather not have to access a menu to turn a synth off. 
 

You are welcome.

Yes, I absolutely agree. I believe that I've already posted request.
