I've noticed recently (perhaps as my number of lists and words has grown) that occasionally Skritter will hang when looking for new words to add. This is strange as usually I have a hundred or more words awaiting reviews, and also have just one or two lists that regularly have new words - so why would it hang? It can take more than a minute while it scours for a new word.
Ok, it's nothing feature breaking, but it can be distracting, and I'm curious if it has something to do with the way that I'm organizing my lists or because I'm getting to a level where I have more characters in my words (which maybe requires checking when adding new ones?).
