I am a first time user.
I thought I’d say something about the waiting!
Though it’s a bit frustrating, I actually think it’s great for those of us like myself who find it really hard to delay gratification. This is already teaching me to be patient and to not go full speed.
In the past when learning Japanese I would burn myself out. The intensity of it all would eventually fizzle out and I’d become ‘disinterested’ (it wasn’t disinterest, but overwhelm. I just packed too much in too quickly).
So, yeah, this is good for us who need to learn to be patient!
I have about 4 hours to wait. 
I do all my lessons at once…or rather in 3 large chunks. All last level vocab + radicals. Then all kanji. Then all new vocab. Done, within a couple of hours!
I have a Yotsuba manga in Japanese that has been sitting there for a while waiting to be read.
