For sure, but I just want to see the list of existing tags in the current Notebook while I'm note-creating so I know what to tag my current note! :-) This is getting off-topic but so you know a better way (only current way that I know of) to do that is to click the little tag button next to the Notebook drop-down you mentioned. It takes a couple tries but eventually it shows a filtered list of Tags by current Notebook. Back on topic: I did download the current pre-release and the shortcut toolbar is back. Huzzah.
