Every time this comes up it’s always a discussion on “abuse” as if users are monkeys that only do the wrong things all the time. Ban alcohol because people abuse it yo.
Personally, I learned a good bit from using undo scripts. It’s not just being able to fix mistakes, but also from being able to mark stuff wrong. Times where I could remember a keyword, but not the keyword I wanted associated with a kanji or term. Or times when I used Bunpro SRS and there’d be multiple valid answers I want to try. Of course, there was also the random mishap like fat fingering the virtual keyboard on my phone or whatever.
However, I’ve also switched to JPDB which doesn’t have an undo button and happily use it… because that service doesn’t suffer from the same design flaws as WK. When we talk about things like “abusing” scripts for progress here it’s usually because people don’t want to get held up in their learning process. WK is freaking awful. Levels progression dependent on kanji progression dependent on arbitrary radical nonsense… missing a single thing can set you behind for a couple days for no meaningful reason. It makes the workload uneven if you get stuck at something like 0/0 instead of having consistent lessons + reviews every day.
WK’s content body is fantastic, but actually using it is a headache and filled with little design annoyances that are often addressed by scripts. I see little to no reason why minor features like this can’t get official support hidden in an advanced menu. Extra study was a much bigger feature, one that people also claimed was bad for learning (LOL) and had room for abuse (LOL), but it was accepted pretty quickly in the end.
But since I’m pretty pissed off and just want to insult must of the people crying “abuse” yall sound like conservative republicans living in fear of the boogey man. There is a portion of the community that is crying out about how they would benefit from this, but yall seem incapable of empathizing with direct statements over it because you’re still scared of a few negatives (LOL).
