Ability to drag a tab into a new window.

[Imaginary-Narwhal]

Describe the project you are working on

No actual project, just a general feature request to make working on games on multiple monitors easier.

Describe the problem or limitation you are having in your project

Stuck in one window on a single screen.

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

Grab and drag a tab outside the main Godot window to create a new window of that single tab.

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

See above

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

No, this is a request for the Godot IDE itself.

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

I don't think a library could do this.

You can already split docks into their own window (click the three vertical dots next to each dock), along with the script/shader editor (click the "two windows" icon in their top-right corner). Note that you can't do this if Single Window Mode is enabled in the Editor Settings, or on Linux if using the native Wayland backend due to current limitations.

Either way, more complete multi-window support is already being tracked in #1508, #7233, #7984 and others.
