Yep, not pro-mesh, either. The prim is the basic building block and is useable by anyone and everyone, regardless of skill level or learning.
Btw, I've been checking out Niran's a bit more the last day or two and it looks like I may switch to that for using on my Workshop. Mesh, .001 nanoprims, some really good graphics capabilities while Phoenix/Firestorm allows only .01 nano. Its UI is v3 but that also seems to be the way the metaverse is going.
