I just noticed that there are File, Edit etc. menus under the script editor tab!
How have I never seen those?! It probably registered as some kind of visual clutter, bread crumps or something like that to me which made me completely overlook those menus. And I always found it a little odd that there was no classic File menu... 😆
There are so many options and commands in there that I have actually been looking for! I always went into the editor settings and looked for keyboard shortcuts...
I feel like an idiot! 😆

But seriously, why would they hide that menu there? There's enough space in the main menu bar. 🤔
