PERMANETLY mark a word as difficult

It’s kinda annoying that I mark a word as difficult, review it ONCE and it’s removed from difficult words.

“Difficult words” should be “I have been having issues with this word for a day or two, DO NOT TAKE IT OUT UNTIL I REMOVE IT”. A lot of difficult words are not learned with one review.

Was kinda hoping that was a feature of subscription.

Not sure what platform you’re using, but on Android, a word manually flagged as difficult keeps its status until you remove it again. And, sadly, there actually seems to be no way to get the DW-status to work automatically once you manually changed it …

IIRC, difficult words are only available with subs.
