Hi Tom,

Hope grant writing is going well!

I have a suggestion for Chimera/ChimeraX - would it be possible to add a clipping mode where the clipping planes adjust with the scale factor?

I realized this is what Coot does, and one of the reasons why I like it for navigation - I can zoom out, and all the molecule is shown (unclipped), but as I zoom in, the clipping planes get closer together - meaning that I can zoom in on a residue in the middle of a molecule, and not have to manually adjust the clip planes to hide all the stuff in front and behind it, which is very intuitive. Obviously this only works when the center of rotation is symmetrically located between the clip planes.

Cheers,
Oliver.
