I enjoy a lot quite a few of the tools Google creates. But there is one thing I really can't belive they still have not fixed. Filters in Gmail. I really, really need some kind of regexp or wildcard filtering, and this is still not available. For instance, I like to be able to do stuff with mail from 'name-*@some.domain' or '*-dev-owner@some.domain' or even use the '*' in the domain-part. But this seems to be quite impossible.
It's a sad thing. Please fix it!
