Quicker coloring - new color tool mod - Pop Up Color Wheel

What I’d like to see:

a new color tool modifer, such as alt+shift+ click, pops up a color wheel right in the session. If you alt+shift+click+‘HOLD’, the wheel pops up, you move the cursor to the colour you want then ‘RELEASE’ and it selects that colour.

If you don’t ‘HOLD’, it still brings up the colour wheel, but you then have to click on a colour, and you get some extra options - selecting a shade.

Other features would include, already selected colours being displayed as a circle+dot in the colour wheel.
