Quick Eyedrop action. Similar to Aseprite, holding ALT will swap current active tool for Eyedrop. releasing ALT would go back to previous active tool. Even if you click ALT it would altopick the color from the current cursor position will also help a lot! Another thing would be color pick from other places/ objects. That could help a lot with larger color palettes. this way I can import a plane-as-mesh or image-as-reference and leave it on the side of my current editing object. This will match perfectly with the quick eyedrop action!
