This may have been covered in a previous topic so apologies if it has, but it would be really useful to know which words I am studying are not yet known.

I can look at my totals in the progress page and see I have added a number of words and I know a different number of them. It would be good to be able to find the missing words so that I can possibly work on those words in other ways.

Is it possible or is this a feature request for the future?

thanks,

The totals are sometimes off by a bit because there are occasionally missed data updates in there, so don't treat them as exact and look for, for example, two missing character writing items compared to your character tone items.

Also, we don't have a way of sorting by learned/not learned any more, since it was computationally expensive when saving reviews and not very useful, but you can look at the words coming up next in My Words, and all the non-learned items should be ready or due within the next twelve hours (since "learned" here is just getting the interval over twelve hours).
