Sorry for taking so long to respond.
I'm not sure I completely understand what you're suggesting. Will you give me a bit more detail so I can pass your feedback along to the team?
HSB color picker = Hue / Saturation / Brightness (so the values can come from Photoshop/Illustrator)
While they're at it, how about a HEX color picker too.
As far as shapes are concerned, you can create your own with Adobe Capture & graph paper. Otherwise, just use large square for straight edge.
I understood the HSB part... I just didn't understand the rest of it. Do you think he's looking for a tracing function.... as in Illustrator CC? (You probably can't read minds.... )
