Text/Visual shader editor in separate tab

[TrickyFatCat]

Describe the project you are working on

N/A

Describe the problem or limitation you are having in your project

At the moment shader editor is a separate from the code editor. In addition it's a part of down panel, which is very counterintuitive and not very comfortable to use on laptops with small display.

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

It would be great to move shader editor to a separate editor tab like other scenes. It also can be a part of this proposal #14

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

N/A

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

No

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

It's a huge UI/UX change which requires changes in the editor.
