Display ALL Scene Materials as Hardware / Standard Toggle
I'm not sure if anyone's done this one yet (couldn't find exactly this while searching), but what I'd like is the ability to change all curently viewport displayed materials from "Hardware Shading" (pink icon) to "Max Standard" (blue icon)shading.
The reaon why is that there seem to be display issues when there is a mixture of these in a scene (some materials using "standard", some using "hardware)... Some displayed materials will drop to black, white, or completely disappear (invisible) in the viewport.
I'd also be fine with something that just "nuked" hardware display on all materials.
