Allow closing the extension from the extension view/toolbar itself

[Yvad60]

It will be useful to be able to close the extension from the extension view itself without needing to click the extension icon again, especially on a browser like Arc where extensions are not always visible

For example, having an "X" button somewhere in the extension view and the view gets removed when the button is clicked

Oh nice, like a close button on the toolbar. Makes sense!

fwiw, you can right click anywhere and show/hide without going all the way to the extension icon

but i hear ya, and appreciate you sharing the feature request here!
