How many times do people need to be told - DSON is DAZ code. 

SM can not legally reverse engineer it and add it to Poser (thanks to the DMCA). Let me repeat and rephrase that because it sounds important:

Due to the DMCA, SM can not legally reverse engineer the DSON code and add it to Poser.

Better solutions:

1.  DAZ hires better software programmers and makes DSON work seamlessly as an add-on.  After all, that was the whole purpose of the add-on framework was to enable niche capabilites such as this to the core system.  Or

2.  DAZ asks Hivewire3D for tips and techniques on how to make their figures cross-platform compatible, since they were able to do it. 

Of course, this would require DAZ to do the heavy lifting on their figures, and what are the odds of that?

I use the face room - it is certainly worth having - it would be even better if it was clearer on how to consolidate changes made in the face room to an INJ.

I also use the hair room (albeit to make shag carpeting & grass as opposed to hair.......)

Things I would like to see in Poser 2016:

1.  Wardrobe Wizard moved off the main thread and onto the add-on frame work.  That way, I could use it while working on something else on the main thread.  (In the past, I have had it tying up Poser for over an hour while converting clothing.  There isn't currently a way to know how long a conversion will take until it starts.)

2.  I'd also like to see a native ability to take a dial-spun character and be able to click on a CREATE INJ/REM FBM in the figure tab.

As far as those who want to remove rooms -

There is already a version of Poser for you - it's called Poser Debut (multicore aware, Poser 4 feature set & Poser 8 code base).  For a lot of folks, it is the version that they really would be happy with. 

It lacks those pesky rooms and advanced features that have been added over the past decade.
