If you want to search the cards with the "Search" function, only hits in the Mosalingua flashcards are displayed. Flashcards created by myself do not appear among the hits. If I now create a new word, I don't know if it doesn't already exist and the card might simply not have been learned yet. In the meantime, this has led to numerous duplicates in my app, since I can no longer find my own flashcards and further edit and improve them (e.g. add the perfective form for verbs), or a manual search is enormously time-consuming, since the flashcards are stored according to the order in which they were created and cannot be ordered alphabetically, for example.
In addition, it would be good to be able to delete own erroneous flashcards (so far they can only be deactivated or you have to overwrite them with another content).
I don't know if this also affects other apps and language directions - I use the Russian app on Android (coming from German).
