Allow users to import their existing Anki flashcard decks into LingQ, so vocabulary and phrases already learned in Anki can be carried over and integrated with LingQ’s SRS review system.
There is already an unofficial ANKI addon that sync to and from ANKI, I am not sure if it works with your own deck in ANKI. Maybe LingQ can work with the author to improve it. LIngQ could also create a folder system (or maybe through tags) inside vocabulary to keep the vocab from ANKI separate from LingQ vocab mainly for easier management.
