mailboxalert 0.15 a
It’s been quite some time, and it will be quite a bit more, but I have restarted work on Mailbox Alert. I’m just about rewriting the whole thing to add a few much requested options. Don’t exactly know which will make it into the next release though, just hang in there ;)
In the meantime, someone told me of another configurable notification tool, Notifu. Haven’t tried it myself, but it looks really nice.
