After opening menu, ↑ could move focus to Settings entry

[szpak]

After opening the extension menu, ↑ (up arrow) could move focus to the last element in the menu (Settings) - instead of doing nothing . That would make it easier to clear history/toggle private mode or enter settings, but also reach to oldest elements on the list. This would be especially useful for people opening that menu with a keyboard shortcut.

Similarly, it could be possible to being in the Settings entry move to the top pressing ↓ - an effectively circular list.

Btw, I'm really glad that your extension works with Wayland (many other clipboard managers do not :( ).
