[Opensim-users] Some questions about inventory libraries

[Impalah]

If "soon" means the next 2 weeks, probably not, at least from my part; but
I'll need to fix these behaviours for the project I am working on (not
urgent, nor essential but important for consistency of a grid).

Extend "soon" a couple of weeks more :-)
