I've been able to get the following apps working in the new GVM and launching from direct shortgcuts in KDE:

Unit2Unit (a handy unit convertor)
MWcalc (a molecular weight calculator)
and WWcalc (a Weight watcher's points calc and tracker)

I've really missed these little tools!

I did manage to get the game Titanic installed also and played for a while, but when I went to open it again, it crashed.

Has anybody tried Legacy or the Quest yet?
