Update on .lev support: I was able to convert battle4 and race4 to 1.23! That's just opening code, and unfinished opening code at that; conversion and saving haven't even been touched yet. I think full .lev support will be the last feature to add prior to the first test release, although I've got a number of bugs and stability issues to track down before that too.

minmay: If you find some links to utilities that use that checkbox (preferably with accompanying documentation), I'd be happy to take a look at them and think it over.
