IMHO we should not remove any "unnecessary" information until the user explicitely chooses it.

It is fairly trivial to write a plugin to remove the unnecessary color-information. Either steal code from the semiflatten plugin or extend the semiflatten plugin to export a second PDB-function to remove the UCI. If nobody else works on this currently I can do this this weekend or so. Bye, Simon -- [EMAIL PROTECTED] http://www.home.unix-ag.org/simon/
