I'll get right to the point.. (Okay everyone, stop celebrating!)

1. Option to use regex for filters. Especially useful for email and IP filters. Having to ban 12.34.50.* to 12.34.79.* is a pain in the bum. Using 12\.34\.[5-7][0-9]\. would work so much better, as would ".*@(hotmail|yahoo|msn)\.(com|co.uk|ru)"

2. Be able to use "?" as well as "*" in ban filters. While not as wonderful as regex, being able to ban 12.34.5?.* would cover 10 spots quickly.

Built in import/export function for ban filters too please. :D
