I've been playing with your project and it is really nice to be able to create "image occlusion" in a browser! There are some interface limitations related to the medium you chose, however, it would be useful to be able to regenerate cards, but discarding all previously generated cards (not adding another cards).
My use case.
- Crate some masks and 10 generate cards.
- Import into Anki
- Spot some issues
- Come back to image occlusion and fix it
- Click "regenerate" button
Expected result:
There are only 10 new cards in a generated (and exported) deck.
Actual result:
There are 20 cards (including 10 new and 10 old).
