Many people have requested for a way to self report their answers as wrong during reviews. Inevitably, this leads to people recommending use of the double check script. The problem is that the script is very brittle (as many people recently found out). I think having a way to self report answers as wrong would be beneficial, but I have a variation of that suggestion this time around, which achieves that goal and a little more.
My suggestion is for all radical/kanji/vocab pages to have a Demote button. This would work similarly to the Resurrect button which is available for burned items. The difference here is that the Resurrect button sends the item immediately back to Apprentice 1, whereas the Demote button would just drop the item by one SRS level.
This would allow people to effectively self report their answer as wrong by demoting the item twice (once to get it back to where it was and once to mark it wrong). But the added flexibility is a bonus since it would allow people to drop the item by as many SRS levels as they want.
What do you guys think? Who knows, maybe @viet and company will like this idea.
