WaniKani Reorder

wkreorder.js
/**
* 2018-04-25
* WaniKani Reorder - wkreorder
* Reorder your review items on the fly
* (Optimized for phones)
*
* With wk-reorder, you're able to - tada - reorder your review items by some criteria.
* As of this script, you're able to reorder them by SRS level, and type.
* The script works by getting your current queue, and applying a sort function to make it
* show items in the order you want them to - either ascendingly or descendingly.
* For this first version, there isn't a nice, clean UI from which you can select the
* ordering, but you'll be presented a prompt asking to enter how you want to order it.
* Type sorting order is radical, kanji, and then vocab items.
* Example sorting strings:
* ・ st
* ・ Sorts by SRS level, and type (all ascending)
* ・ t-s
* ・ Sorts by type ascending, and SRS level descending
* ・ -st
* ・ Sorts by SRS level descending, and type ascending.
* By default, readings will come first and meanings second. Radicals are meaning-only
* items.
