Whew, this one took a while. Around three years of development went into OpenMW 0.49.0 which is now available to play Morrowind with lots of enhancements.
Looks like it is time for me to start another Morrowind run and not finish it <3
Don't remind me... I've got the main quest basically complete - but I accidentially found Sunder before I knew what it was good for and lost it. No idea where. Gave up on it but I certainly don't feel like starting up again.
You mean something like item.add (or whatever the syntax is)? No luck with Sunder so far - and the map editor doesn't run with OpenMW as far as I know.
