[chimerax-users] Coulombic color combined surface

[Elaine Meng]

That's great!! 

We understand it could be confusing (and annoying if you don't know how to stop it with this "surfaces" option) that the surface you already made would get thrown away and the per-chain surfaces would reappear.

You're welcome,
Elaine

Even though I  generated a surface of combined chains by "surface enclose" command, ChimeraX still colors each chian seperately. In Chimera (not ChimearX), I could use surfcat to combine chains, generate one surface for combind chains, and color the surface as one continous. However, that could color large set of molecules. So please make ChimeraX can do the same.
