Indeed swapping the images was easy and intuitive, I should have added that. The "ugly language" was a bit unexpected, as in general the support for Dutch is surprisingly good. Maybe the combination of the prompt and the translation, and the mixed used of languages. Perhaps if all the prompts were translated to a language of choice (an the user would be prompted for a language) it would work better. But maybe you never even considered making a multi-lingual tool, and just out of the box it more or less already supports that. This would have been unthinkable just a few years ago, truly amazing!

How do you combine a (full time?) teaching job with building such a tool? It feels way more than some hobby project. Congrats on the release!
