I disagree with BRX. That's imho not a good place. 1st: that would be in the search bar that can be switched on and off. The current library has nothing to do with search functions. 2nd: on a small display in portrait orientation the search field is not so much too long as it might sem on a big large display.

I think that it's not necessary to display the current library all the time on top of everything as users won't change it all the time. Maybe it's enough that we can look up the current library with one click (or maybe two), just not hidden do deeply in the settings. How about a new menu item in the "three dots menu" top right? It could be named "Switch library" in case only one library is configured and show the name of the current library in case more than one library is available. Clicking it should open the "switch library" window.
