Allow moving an embedded Window by dragging its sides instead of resizing it

[DragonMaster14545]

Describe the project you are working on

Im currently changing a lot of my menus to use windows, because that just feels better imo

Describe the problem or limitation you are having in your project

It is really easy to drag a built in window of screen, at which point you can't get it back on screen or close it.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

I suggest that if the user double clicks on the side of a window, which would normally resize it, it instead allows the user to drag the window around as if they clicked the top bar of the window

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Double clicking the a side of the window allows you to move it

If this enhancement will not be used often, can it be worked around with a few lines of script?

No, I have not found a good way to do this

Is there a reason why this should be core and not an add-on in the asset library?

This is a qol feature for built in windows that should not require an extra addon from the asset library
