I use my filter to select a specific subset of words depending on status, as is designed into Lingq vocabulary already. For each status I have allocated meaning. I am specifically interested in the division of total known words between status 4 and status 5 (or K). I am however interested in the volume of every filtered set.
So, if I select status 4 only, I would like to know how many occurrences are in the set. The same goes for status 5 (or K). This gives me respectively the passive vocabulary volume and the active vocabulary volume.
Currently I am very interested in tracking the growth of the active vocabulary as that indicates in important aspect of progress for me.
In lingq one can currently not track these amounts. Browsing through roughly some 14000 list of known words, 200 at a time, is impractical. 200 is the max amount per retrieval.
Also, wanting to retrieve somewhere in the middle is equally impractical. It would be a good idea to be able to retrieve from a specified number onwards. This gives me the chance to review the list other than at the pure beginning of the list.
So, the request is:
  1. Add a total number to the result of a filtered set of words giving the volume of the set.
  2. Add a number at the start of the retrieval to start retrieving from within the set.
