I really like the SRS built into Readlang which saves me having to export words and import into Anki.
That said, there is a lack of control over the SRS cards vs Anki. I realise Anki is literally only an SRS app but I feel like in Readlang it would be great to have a bit more control, for example being able to see upcoming reviews, understand a bit about how the algorithm actually works (for example if I answer correctly , how long is the next review) and see how many cards in total and their review statuses.
Have you considered adding any such features?
