Must-have scripts/extensions/apps for beginner

These are really just a matter of convenience, but I think these are worth checking out the most:

Dashboard Progress Plus
Ultimate Timeline
Additional Resource Links/Stroke Order
Mistake Delay
Similar Kanji (though this site is a much more comprehensive method of looking for similar kanji: here)

Chrome Extensions:
Wanikani Notifier 
Wanikani Companion

Apps (if Android):
Wanikani Mobile

I know people might throw in ones like Override, Double Check, Reorder, etc, just my opinion, you really shouldn’t need those. Good luck!
