This would be great if it: a) Open some Linguee interface, not its website, on the sidebar. b) Put an entry in the right-click menu to translate some text that would go to Lingue and displayed in the sidebar. As it is now, it's ugly and not very useful.

Such a great tool !
It's really light and doesn't need any authorisation. I use it with the shortcut to open the sidebar on Linguee only when I need to translate something.
Excellent!
