That's nice, I'd use separate buttons and contents in one of my TWs were
TW5.

Well, I suppose this can be done in a quite simple way:
+++[label tab 1]
contents of the tab 1
+++[label tab 2]
contents of the tab 2
...

I guess one would hardly need "tabs" with one tab; and, at least in Eric's
implementation, nested sliders can't be used one inside another.

Well, I guess the implementation can be grabbed right from the
NestedSlidersPlugin (with "unnecessary" part removed), although I don't
know how those "rules" are processed and whether they have names/can be
hijacked (I mean, if Eric reimplements NestedSliderPlugin for TW5, it
should substitute a simpler "rule").
Best regards,
Yakov.
