If you don’t touch WK for a period of time (preferably have it customizable. And an option to enable/disable this.) it will automatically go on vacation mode. This will help people get back into WK when they take a break.
Maybe a max review per day feature (customizable and have this on or off.) To help make the review pile less daunting? But still have the option of doing more and a clear notice that you hit your max review limit and you’re not actually out of reviews.
That would have two benefits, help people go through a huge review pile at a steady pace. And also encourage people not to spend too much time on WK and neglect other areas of study.
Or instead of the last one maybe instead of a reset feature you can pause items past a certain level to keep reviews down? Particularly useful for people who were away for awhile (Obviously It should disable new lessons as well, while active.)
Lastly I’m mentioning this just cause why not? An option to turn on or off an undo/typo button. (Maybe with limited uses?)
Moreso throwing this out there for fun, since I know it is mentioned a lot. (I’d still like it as a feature though…)
Really not important changes but it could help retain a user base and might encourage more repeating memberships. (That’s my lame excuse of a sales pitch.)
Probably people have already suggested things like these before, especially the undo button, but hey I don’t frequent the forums. Anything else i might say/add are things I know for sure have been said ad nauseum.
