This doesn’t specifically answer the question but might help solve the problem (I had/have the same): I use the script “SRS reorder button”, and use it sometimes when I have neglected my reviews a little bit and thus forgot some older items I had already guru’ed. I don’t always use it but sometimes apprentice items really pile up due to laziness and then I sort by SRS to get them out of the way more quickly. I do this especially if I don’t have time to do all required reviews the same day. The main positive effect this has on me is a psychological one of not being showered in tons reviews every few hours. Just having less reviews coming in in a day allows me to retain the info much better I feel.
Sure. It sounds like you don’t know how to use wanikani scripts in general. Explanation is found here: Visual Guide on How To Install A Userscript
I personally use google chrome and Tampermonkey to run scripts.
