Retain filter for context sentences when reviewing flashcards by text.
When I use the premium feature of reviewing just words for a particular text, it would be great if it only present context sentences from that text.
So if I am specifically reviewing words from a Harry Potter book, I would like to only see context sentences from that book. I would still like to click the arrow to see context sentences from other sources, but one of the Harry Potter sentences should show first. Thanks.
