Very good job, simple, efficient, close to perfect. A few things I would suggest, by importance: - add (customizable) keyboard shortcut - keep the search bar open when going to another tab and then coming back to the one searched - add option for case-sensitivity - add option to keep the same set of searched words across tabs / pages when clicking on the icon Possible bug: shouldn't the counter start at "1/..." and not "0/..."? It looks like it doesn't work fully on the search result pages of linguee.com.
