When pressing the CMD key a color picker appears (this applies for Mac, I think it's CTRL on other systems) .

Currently I need to click on a color to select it. Can I configure the color picker such that the current color gets upated continuously to the hovered color without needing to click it manually? This would improve usability for me a lot as it would always highlight the currently hovered color in the color palette and save clicks.

I just found out that it works when you don't only hover the canvas but keep the mouse button pressed (or put the pen down on the tablet).
