This is not fixing what the issue is describing. It should be a menu item, not a toolbar button. Clearing the clipboard is not such a common need that it needs to be in the toolbar. It could have a keyboard shortcut though, for easy access.

I think we are talking past each other. It should only be in the menu bar, not in the toolbar. There should not be a toggle to show it in the toolbar.

I was planning on asking whether you'd accept it as an option (either as a visible toggle or as a defaults option not exposed in the UI, as it's something I need for myself), but hadn't gotten to it yet. I would also have marked this as a Draft PR if GitHub offered that option to PR authors (both due to not having asked that yet as well as not having the menu option to clear implemented yet). (Nevermind. Turns out the option's just hidden in the sidebar.)

I'm not interested in that. Clearing the pasteboard is not something most people need. Even with a hidden setting, it still adds maintenance overhead.
