Using the Common Colors or Color History command pops up the window on my 3rd monitor, while I have Krita on the 2nd one. There seems to be no way to drag it over, how can I set the position? Thanks

In the Krita Shortcuts, under Krita -> General; the Colour History (H), Colour Selector (Shift+I), Common Colours (U), Minimal Shade Selector (Shift+N) and My Paint Shade Selector (Shift+M) can be a bit confusing when you use them.

They are not windows, they are patches or overlays (terminology?) and they appear wherever the cursor is when their shortcut key is pressed. If you press and hold the shortcut key then you can move them around either on-canvas, off-canvas or onto another monitor. You can also have them all visible at the same time but I'm not sure if anyone would ever want that.

After they appear, they disappear if you don't use them and will stay if you do use them to select colours. Sometimes they don't stay if you use them, depending on where they are or which one you're trying to use. It's impossible to describe their various forms of behaviour, you just have to play with them for a while.

An easy way to have use of Colour History is to select it for viewing on the Advanced Colour Selector docker. Click the options list icon (under the word 'Advanced') and then the Colour History tab and then tick the Show Colour History box. There are various parameters you can adjust.

Please note: The image you posted on Snaggy claims to be a .png on download but Snaggy seems to have compressed it as a .jpg. For screenshots (and everything) it's better to use a service that doesn't compress uploaded .png images.

I understand the intended behavior, but I'm having trouble placing them on the monitor I want.

I draw on a pen display (monitor 1) and the overlay for this tools pops up on my main monitor (monitor 0)

Here's 2 videos explaining what I mean:
Pressing U + mouse click down + dragging on canvas (monitor 1): https://youtu.be/kTfcN4JE72Y
Pressing U + moving around canvas on (monitor 1): https://youtu.be/xIkHHKUv4fg

The overlay doesn't move at all on X axis, just on Y axis and there seems to be no way to drag from monitor 0 to 1. If I move krita to monitor 0 the tool works at intended but I need it on monitor 1.

The pen display seems to have complicated matters.

Have you tried making monitor 1, the pen display, the main monitor? This would require you to rearrange the krita layout but it should remember it.

Would you be happy to accept use of the Colour History (H) and set it as a permananent display at the bottom of the Advanced Colour Selector?

If not, then I can't think of anything else to try.

It would be less than ideal since there's applications I want to run in my 144hz monitor (0) that would now launch on my pen display (1) and can't be moved, but I guess it could be a temporary work around.

Is this a bug then, and should it be submitted?

No... Determining on which screen a popup shows is not something we can influence, it's the toolkit which decides that, I'm afraid.
