That's the beauty of it - it's for submodels, but they don't have to be subsystems. I haven't tested it for turrets, but in the past i've mounted a spinning disc to a turret arm (ie base -> arm -> disc) and that rotation worked fine, so chances are it does for turrets too.

You're correct that the max depth is 5 (though in my build i set it to...7 i think?) and haven't had problems so far. Also under normal use, you shouldn't hit 5 even. ie: Hull -> base -> arm -> cylinder arm, so yeah hopefully that won't be a problem either.

As for a build ETA, errm, a little while due to general busyness, but don't worry, it will come about!

Also, Goober and I have been revamping the docking animation code, which is rather more awesome now! Goob also made a SEXP trigger for animations which i'm sure will be ridiculously useful down the track when we have more animation capable ships around.
