Nothing wrong with scrolling, it's just that I constantly forget to scroll to see just 1 more world... the index looks exactly what it looked like before I got For Rent and the latest world. Perhaps it will feel better when I add Lovesyruck's world, eventually :)
But - with all these worlds, it could be nifty having them sorted in a more logical way, say per climate zone instead of by when they were released. Maybe we could get a customable index, allowing us to sort worlds by whatever system we play by, many of us have grouped worlds as nations or regions. Creating your own grand map would be awesome methinks.
