If there are menu items that you never use in Photoshop, you can hide them by selecting Edit > Menus. Navigate to the menu that you want to hide and click the eye icon (the Visibility button), to toggle it off. If you hide menu items for a category (such as File, or Edit etc.), a new “Show All Menu Items” command will be listed at the bottom. You can click this command to temporarily display the hidden menus.
Note: To make switching between tasks in Photoshop easier (such as painting or working with video), changes made to both Menus and Shortcuts can be saved as Sets (using the icons at the top of the Keyboard Shortcuts and Menus dialog).
