Hello Gem! ๐ That's a great question. You're referring to the menu bar at the top of the screen, right?
You can disable its visibility by pressing CTRL + ALT + C. This hotkey toggles the menu bar on and off. So, once you're done editing, just press those keys, and it will disappear!
If you ever need it back, just press CTRL + ALT + C again. ๐
