Hey I'm currently evaluating this after coming from Lingq, My demand for an app like this is very simple I need a list of all my known words that I can export at all times. Lingq couldn't provide.
1. When trying to export my known words I get an empty text file. (Although it worked yesterday)
2. Vocabulary/Import export is listed under features that aren't in the free version. However it clearly worked yesterday.
I'm gladly willing to pay for the service I just need to know if the feature is there and not in some encumbered way or only in relation to a text. I need all words I ever marked as known.
