Add the possibility to select multiple character sets

[fmonts]

What is your problem
I use 3 languages in my everyday work, while my keyboard is US international.

Describe the solution you'd like
It would be nice if this menu allowed to check multiple languages, and not only one or all:

Not sure if I got it right, but I use 3 languages too. Russian, English, and Turkish. I want QuickAccent to be active only on the English keyboard so I can use Turkish letters. I don't want QA to be active when the RU keyboard is active.
Hope that makes sense, thanks.

I type in English while using Swedish and German accents. If I have the language set to German I won't have access to the Swedish Å but if I have the language set to Swedish I won't have access to the German Ü. If you could pick multiple character sets or pick and choose specific ones that would be awesome
