Sorry theducks but there is nothing "good" about that feature in my opinion. It is completely and totally unprecedented in any application I have ever used - applications do not remove their main toolbar when "context changes" in such a minor way like this. Add a new toolbar by all means, but not swapping out the main one.

Besides which, it should not be a "context switch". Just because I have a device plugged in does not change context. In all probability it could well be plugged in just to charge. That changes nothing about how I want to be using calibre, but this nonsense about adding icons to multiple toolbars *forces* the user into either working differently, unplugging their device, getting confused, or faffing around with the clumsy process of putting icons on multiple toolbars, and trying to keep them all in sync or else icons get moved around just because their device is plugged in.

It is a silly idea that I hate with a passion. But as I have said before, my views on this are based around using and supporting a lot of plugins - and GUI plugins didn't exist when this implementation was created in calibre.
