Yesterday I used the quick add function for the first time - the words got added to 'Miscellaneous' as default which was fine for me.
I was curious what would happen next -- the new system is after all supposed to be the best of both old list and queue and I have to admit that I don't understand it 100% yet.
My understanding was that if you quick add words, you don't need to worry about them anymore - like when you added words to the queue, but they never showed up for me.
I checked and saw that the Miscellaneous list is 'finished' - which I don't quite understand since I never used it and the two characters that I added yesterday are the only items on the list.
