Good idea! We'll see when this gets done, bugs are priority at the moment. :)
Matrices would be a separate topic, as there isn't even a matrix datatype in SF yet

This is potentially fixed in 0.18 now, let me know if it works when it's out :)

Awesome, thanks for the help finding it :)
I'll see if I can get this into 0.18, as it's quite a critical bug!

Ouch. Hm. I've never used an integrated Perforce in Unity before. Do you know of any links on how to deal with file access in Unity when using Perforce?

Possibly yeah. Mouseover to show full version perhaps?

A code node is planned, but I'm not sure if there will be a custom node system. There are however plans for making nested nodes, which would then be able to act like non-nested nodes in your shaders :)

Interesting, I haven't even thought of that. What happens when you try opening shaders?
