I’m forwarding a request from a client of mine to add an “X” close button to the material selections when they’re open. They do know that clicking anywhere on screen closes the panel, but that’s still unclear to their staff.
Another request they had is to be able to add names to each of the materials on the material selector–I do think that would help distinguish materials for the sales staff demoing Shapespark to prospective customers and walking through different material options.
