So, You can add a tag
You just have to switch views. (click the column head to sort or enter the search: ondevice:true then do a bulk edit and Add Tag
BTW Only those WITHOUT a tick in device view, do not exist in the main Library (you might want to select those and right-click "copy to Library" as a backup )
I'm really starting to feel stupid ... can I just replay my steps, maybe I/you will see what I'm missing???
1) Device pane - I select a dozen or so books (e.g. in the Collection "To Read", but they can be any books...).
2) Double-check: they are all "In-Library" ticked
3) I switch view to Library pane: there, I find selected whichever book I had selected before
going in the Device pane, in step 1), so no way to edit metadata for the set of books selected at that step
What am I missing????
