When we customize menus or toolbars, we can filter the huge list of all commands, to make the list easier to locate relevant commands in. But - we don't have this facility available when trying to customize the notebookbar(s).
Note that the available customization for the MUFFIN Notebookbar assemblages was implemented at 6.3 release in response to bug 101513 Control remains a simple list to toggle visible or hidden each of the UNO controls added to the assemblage. Some suggested consolidation of the customization with bug 148121 But as noted, the ability to influence the NB assemblages is pretty limited. The whole half-baked NB UI framework needs major refactoring to ever reach parity to Menu, Toolbar, Dialog, and supporting Sidebar decks MUFFIN assemblages.
Make that as available at the 6.4 release, not 6.3
(In reply to V Stuart Foote from comment #1) Grudgingly accepting this as an enhancement. I agree that the NB is half-baked. And that it could use an overhaul / major refactoring. In fact, I believe that should probably have happened before we even shipped it to users. But - we have decided to make this UI mode highly prominent, an easy and accessible choice on the first start dialog. Which means that a large fraction of our new users will be using it. And that means that short-term quality-of-life improvements are merited, even longer-term work is pending.
I would rather go the opposite way and make the Notebookbar variants static. The advantage of customization is limited to the classic UI (that is by nature way more flexible). Size, position, priority, label... there are many more attributes to consider for the Notebookbar making any customization as complex as hacking on the UI directly. IOW: if the UI would be editable per Glade, fine for me. Pointless for users. => WF

Seems the direction Collabora has taken COOL and the Desktop builds, no customization remains and the "Tabbed View" remains from LO MUFFIN as default, supplemented by their "Compact" view for a contextual Toolbar and Menu feel. Unlikely we'll see any more substantive effort for rework of the sfx2 based Notebookbar framework to support customization, or for other MUFFIN assemblages.
