Interesting, in fork I don't have failed stylecheck action (https://github.com/arkology/godot/actions/runs/15944544374)
Upd: No edits in SVGs - no errors 😆

I'm not sure if this needs a new icon, you can just use the GuiTabMenuHl.

Originally I used GuiTabMenuHl (you can see it in linked feature request issue), but then looked how it is done in other places like Notepad++ and Visual Studio.
If this is preferable, I'll revert it.

I wonder if we need arrows now? I personally don't see myself using arrows when there is dropdown

I think still keeping them is ok because they indicate that there are invisible tabs.

Hello, great idea, in my opinion a good extension of functionality would be to add a search engine, it would be useful when someone has so many scenes that entering the name will be faster for them. Theoretically it could be done using TextEdit, what do you think?

@piotrtrkostrzewski94 PopupMenu already has some kind of search functionality (https://docs.godotengine.org/en/stable/classes/class_popupmenu.html#class-popupmenu-property-allow-search).
More extended search functionality could be added in follow-up pr.

@arkology Thank you very much

Rebased because GitHub was showing conflicts.

I really like this feature. There's a problem on macOS though: the shortcut KeyModifierMask::ALT | Key::L is what you use to type @, meaning you can't write things like @export when this button is present.

@nubels unfortunately I don't have macOS to tell which shortcut is free.
Fell free to suggest another combination.

@arkology ALT+K, ALT + I, ALT + T would work for example. I assume you chose L because it stands for list? If that's to unintuitive I'm not 100% sure if we need a shortcut for this button in general.

Changed to ALT + T

Thanks!
