It would be an enhancement if LyX "native screen rendering" (without
instant preview) made this right for RTL languages.
We can, however, implement correct "leqno"-support without this, as ...

I think, we can safely assume that with "leqno", there is no numbering on
the right side.
OTOH, the *default* is not always right. Left numbering is the default in
"some special classes", but also for (at least some) RTL languages.

I can live without native "reqno" support. However, I cannot live with the
current GUI interface:
The drop-down box
Fromula numbering [Right]
[Left ]
is misleading (it is "default" vs. "left"). We know its wrong for RTL
languages and some classes.
Why not:
[ ] Place equation numbers left.
? (Where do we toggle equation/formula numbering and how is it called?)
