Looks fantastic, congrats on the launch. Using git for versioning and PCB development has been nearly unworkable. So nice to see a visually-oriented solution.
Vulkan (MoltenVK) does seem to be a valid option for those heavily invested or interested in porting existing OpenGL projects (I plan on evaluating it):

Great concept. Would like to see more of this idea applied to neural network processing and configuration in general (which in my experience can sometimes be a tedious, hard-coded affair).
