Rather than bloating Nomad Sculpt with loads of additional features how about developing a suite of apps that work in concert with each other eg….
Nomad Mesh - low poly modelling (basically all the features of Zmodeller in Zbrush) and UVing that updates base mesh in Sculpt, when problematic additional sculpting has been done you’ll be alerted to re-UV the base mesh or show heat maps where UV stretching is occurring
Nomad Pose - Zsphere type rigging, as I believe it’s the most user friendly but if there is a better, easier solution then I bow to more expert suggestions. These poses would then translate back into Sculpt as a Blend Shape layer (such a Morph Target in Zbrush) and being able to continue symmetry sculpting whilst posed is essential
Just my 2 cents, I know it’s a lot of work for a solo dev but I’d happily pay for both of these apps as I’m sure many others here would too, and if some users don’t care for these features then it won’t impact their sculpting experience
