Added! It will be under "Dutch (Belgium)" when displayed alphabetically, but it will appear as "Flemish" in reviews.

I'll work on getting some samples generated today or tomorrow for the onboarding flow, but if you sign up you can now extract expressions in Flemish.

Any chance you would add Dzongkha?

PS: Cool product, if I were in a different life phase I would definitely consider joining you to build it!
