One thing people have been asking that we forgot to mention is that when you disable lists, all the words you added from them won't be ignored, like before. It was too performance-intensive to support that.
So you'll probably be seeing a bunch of old words come up at first, if you had disabled some lists (like the radicals list, for example). What you can do is go to that list on the vocab lists page and start selecting big chunks of it, then ignoring them. It's not the best solution, but there isn't a better way that we can support right now.
But you're out of luck if the list you had ignored is HSK Level 1 (characters), since we retired that list and replaced it with HSK 1, which includes both characters and words. The old list isn't in the new system, so you can't ignore things from it. Sorry!
You would be able to ignore stuff you didn't want to see from the practice page itself, but I haven't finished the ignore interface in the new system, and probably won't for a couple weeks.
You can skip past items you don't want to see for now, until the ignore button comes back and you can ignore them harder.
Let us know if these are serious problems for you and maybe we can hack something together case-by-case. Sorry about this, guys.
