Allow detached editor docks to be split or contain more than one tab

[EricEzaM]

Describe the problem or limitation you are having in your project

1. UI is not flexible (a few other proposals related to this).
2. Now with floating docks, you cannot keep 2 docks in one window. E.g. "Inspector" and "Node" by default exist on the right hand side of the main Godot window. If you make Inspector "floating", it creates it's own window. If you make "Node" floating, again, it is in it's own window. You cannot combine these two to make them into one floated window with tabs - it has to be 2 separate windows. Lame!

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

Dockable UI. See the dockable UI system for Qt. It is probably way overboard for what we need, but that gives you an idea of what I mean. https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System

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

Currently, the Inspector (for example) just opens in it's own window. It is not inside a tab container.

Off the top of my head, I think maybe we would need something like EditorWindow, which inherits from Window and has the ability to do this sort of splitting stuff.

To begin with, it is probably just worth the drag and drop of 'tabs' working first (green in image above).

Hi !
I'm facing the same problem. I wanna arrange docks together on a side of the screen since the screen is vertical but not possible and now that I see your report, I'm wondering when it will be integrated.

I'm wondering when it will be integrated.

To my knowledge, nobody is currently working on implementing this.

But when I think about it, it's not that complicated since we can already make a dock buoyant, we can make a dock container to assemble them together.
Thanks, I'll be wainting.

Not actively, but we're refactoring the internals of the editor GUI with this potential feature in mind.
