•  network rendering of a singleton render
•   multithread everything we can (cloth dyn sims, physics, all render passes...)
•   "mesh light" property setting - the object would cast IDL in proper proportion to its ambient strength
•    particles - with my own UV-mapped OBJs, and with "mesh light" properties set on a per-material basis
•     option to keep imported OBJs remotely referenced (not embedding the geometry into the pp2)

1  By networking out a singleton, I mean Queue Manager distributing buckets amongst the remote nodes (aka "RenderCows", "render slaves").  Vue's HyperVue network render controller does this.  Most Poserites don't animate, but everybody makes big final renders.  Networking a singleton by distributing buckets would suddenly make Queue Manager very attractive even to users who never animate.  Imagine being able to add the power of your old computer, the laptop, and your hubby/wife's computer to help your main work computer on finishing a high quality wallpaper render.

2  Multithreading:  just look for any processes which are  time bottlenecks due to single-threadedness, and multithread those processes if feasible.

3  How many times have I seen someone struggle to make a glowing object, because IDL does not respond to high ambience as our eye sees it?  The item doesn't effectively cast light unless it is hyper-ambient (several times greater than 1), but if you set the visible prop with this much ambience, it burns out to a white silhouette.  So, a "mesh light" property tick box would tell Firefly to cast much more light from this object (or material zone) for a given value of ambience.  Thus, your mesh light lamp could have a soft warm glow with an ambience of 0.67 and it would cast an effective amount of light in IDL.

4  Particles - the old utility only used procedurals and one mat zone (preview).  I want to be able to use my own OBJs, retain their UVs and multiple material zones, and to make flames which actually cast light, I  want to be able to designate mat zones as "mesh light".

5  Let's relieve the content maker of several unnecessary work steps.  When I import an OBJ and save it as a prop, I want Poser to offer the option to retain the OBJ (and its .mtl file for users of other studios) as a remotely referenced OBJ, to be placed and named as I choose.
