[Chimera-users] Thoughts re enhancements for ChimeraX

Hi Tom, I like your solution re selecting the opaque thing by default! That
would work well, assuming that meshes are treated as a special case
(treated as transparent even if opacity is set to 1). And I would suggest
that models should trump maps, regardless of transparency.

Agree re minimizing modifier keys for essential functions - but they can be
handy to expand the scope of things that can be done quickly for expert
users. Likewise being able to bind aliases to customizable key bindings
would be wonderful - I use these a lot in coot and they save a great deal
of time (e.g keyboard shortcuts to bring up specific panels, like render by
attribute, would be great).
