I disagree. The only scripts that can break the work flow are reorder scripts and override scripts, and only when abused. They’re intimidating because script abusers make “Should I reset?” posts, but the silent majority of responsible users who enhance their study with scripts don’t need to make “Hey guys, everything’s great and I don’t need to reset!” posts. This argument is the same as “Some people took L. Ron Hubbard’s work a bit too seriously and were harmed by it, therefore books are dangerous and I wouldn’t recommend reading any.”
There are plenty of completely benign scripts with no potential for harm. Here’s the ones I use. I’ve deliberately omitted any that could even maybe be abused or encourage unhealthy gamification, because I agree that the ones you have in mind aren’t a great idea for everyone, and each user needs to decide for themselves if they can handle that.
Scripts I consider essential. Ideally if these were part of the base experience, I think WaniKani would be better for it:
Jitai - Randomizes Japanese Fonts in WK lessons & reviews
Pitch Info - Displays pitch accent information in lessons & reviews
Katakana Madness - replaces hiragana for on’yomi with katakana; only affects kanji, not vocab; This is standard practice in most dictionaries, subtly informs and reminds you which readings are on’ or kun’ and provides much needed Katana exposure
Stroke Order Diagram - displays stroke order in lessons and item pages
Minor convenience scripts to install if you feel like it, in descending order of significance:
Ultimate Timeline
Hotkey for other voice actor
DotDotDot Expander
IME2 Furigana
Lesson User Synonyms 2
Like Counter
And then there’s the Heatmap. It’s rather ubiquitous, and potentially a great motivator and tool for analyzing and improving your own study habits. There’s not really any risk of unhealthy gamification with this one unlike with the [REDACTED] script. Good luck. 〜(￣▽￣〜)
