Great and handy tool !

Just a pity that it can't been used as a dictionary toggle, i.e. clicking a dictionary disables the others instead of having to select a dictionary and having to disable the other(s)

This review is for a previous version of the add-on (3.2.4).

Hi! Thanks for your positive review! <3

The dictionary toggle interface does not belong to this extension, it's Thunderbird native interface.

Having said that, Thunderbird and this add-on support selecting various languages at once since last year. Maybe you need to update Thunderbird?
