[PixelTim]

Describe the project you are working on

A game with lots of scripts

Describe the problem or limitation you are having in your project

It is not possible to hide the method list panel(that is below script list)

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

Add a option in "File" dropdown list to hide the method list panel(like button that hides script list)

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

Pressing the "Toggle method list" button will hide/show the panel:

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?

This is core

There is text_editor/script_list/show_members_overview editor setting:

Ideally, it might be dynamically toggle-able with an arrow icon (like the entire script list is currently).
