ALWAYS Display Notebook Name
The tabbed interface is fine when you have multiple tabs open. The non-tabbed interface never shows the notebook name. This seems like a pretty fundamental UI function.
I have 8 categories with over 50 notebooks total. I constantly need to back out of a notebook to get back to the "Categories" UI to make sure I'm in the correct notebook unless I have multiple tabs open.
The tabs just take up screen space I would rather have as usable.
I know this has been requested before but the requests are pretty old.
