You can move the Fill window but the quickest way is to not open the Fill window at all, just press i to call the color picker when you have something selected. (Not trying to invalidate your suggestion, just offering a workaround for the meantime.)

It’s so disturbing when u want to change the color of some object, the color picker appears on the workspace which makes it hard to use the pipe to get a color from your workspace

@Lamia_Bakli Hi! I saw your original topic, and merged it with this one. Does Gleb’s alternative work for you? Understand that it’s not a ‘fix’ of any kind, but maybe it will help address your need.

If not, feel free to reply here with additional feedback.
