just a little idea for the Interface
I do have often to change Between Several languages; So i had the idea:
additional / instead of the language preference under match preferences, - how about give it its own Little flag button under the Match on the main frame
less C liking, & you are SEEING which language is selected at the moment.
interface preferred Language Selection
Re: interface preferred Language Selection
I recommend making Presets for your various database / language / etc configuration sets that you're using often so you can use them via keyboard shortcuts.
