--No button to enable/disable this extension, so it's just on all the time, even when it's not wanted/needed.

--Despite the supposedly many settings, I still can't figure out how to make the default zoom larger or smaller

--Changing settings seems to do nothing, despite clicking "Save" when finished??? For example: Unchecking "Move pop-up with the cursor" doesn't change the behaviour at all. The pop-up window *still moves with the cursor even after unchecking this box.
