Ohh, did they put boolprop back in for Sims4?? Oh man, so happy to hear that!
Sims2 OMSPs are annoying, although the newer shiftable ones are a lot easier to work with. I just wish they all automatically changed invisible when you go to live mode like the Sims3 ones do. I haven't used any of the Sims4 OMSPs. Kind of feel like they aren't as necessary now that we have the moveobjects cheat and can shift things up or down with certain keys. I just wish the increments were a little smaller, but perhaps that's why people made the OMSPs in the first place.
