Hey Stephane,
Sure, go ahead and make the script available on your site.
For the short-term I'd prefer to leave the default behavior in
VMD 1.8.2, but we can see about putting this into the version
after that. (too many changes at the last minute are a bad idea...)
Along these lines, if people have graphing scripts for packages besides
XmGrace, please let us know!
Thanks,
John Stone
