Visual ready-for-review indicator for items on the dashboard

I do not get your question completely, but there is a bunch of usefull userscripts that will:

  1. Show upcoming reviews:
    [Userscript]: WaniKani Ultimate Timeline

  2. List all apprentice items grouped by level:
    [Userscript] Dashboard Apprentice

  3. Allow you to run drills outside of WaniKani SRS on items of your choice, including leaches:
    [Userscript] Self-Study Quiz

Hope it helps.
