Sounds like you're currently getting in tons of good, new features.
One feature I'd like to see is the ability to filter out Foreign Language cards in the 'start-up' settings so that I don't have to enable it every time I start the program. It would be nice to have a way to permanently opt out of displaying cards in certain languages from a list, or if it is easier just opt out of all non-English.
I know lots of people buy other language cards, but I personally don't need to see listings for Russian cards in the collection window when I'm scrolling around. It just takes up space because I'll never own any Russian cards.
