Hi Michael, all,
I'm just going to call it "ribbon" in Gaelic, not sure why LO had to go
with a new word here anyway, everyone hates it as "the ribbon" 
lol, I'm sure you don't want your users to hate LibreOffice
I really
like the way Mihkel and Martin are taking, the idea of combined or
hybrid, I think it really reflects where we want to go with this multi
things interface.
Interestingly, originally it seems to have been called "non-tabbed
toolbar", dunno if that creates issues with those translations that
called it "tabbed/with tabs something"
https://en.wikipedia.org/wiki/Ribbon_(computing)
Yes Jean-Baptiste is right, depending how you display the toolbar, there
could be no tabs appearing.
Hence I think the correct translation is neither ribbon nor tab something.
I really don't know why the UX team had chosen a name that means nothing
even in English.
Cheers
Sophie
