I don't recall exactly but ...
I don't think there are many 2D formats that are supported.
I believe that 2D .mol files are supported ... only because the Z-coordinate is always 0.00
Probably 2d .cml files too ... but I don't actually remember.

OK

I agree.
Good. At some later stage we can talk about event models (e.g. selection in one can highlight the other, etc.) Note that atoms can be mapped even if the coordinates cannot

OK

If others agree, I think it may be a good idea to put some 2D viewing into Jmol ... Jmol is for viewing molecules and it would be nice to support the display of 2D molecular model files.
(Certainly there would be no editing ... as in JChemPaint)
From my perspective, if we were to do this it would need to wait at least a few more months.
FWIW Chime has/d a 2D option (I think).
