The level of detail in the GUI is a matter of constant debate. The
underlying programs are far far richer, so the question is how much to
expose in the GUI. We try to get a balance between ease-of-use and
coverage, but it won't always work. BTW I don't think we ever claimed
that ccp4i (or anything else in ccp4) is "finished" ;-)

Having said that, we're always happy to hear about specific defects in
the GUI. When reporting these to [EMAIL PROTECTED] please give as much
information as possible, in particular knowing the context is always
helpful.

Cheers
Martyn
