yet another post about gmail first impressions

Now that I've made the plunge and switched entirely to gmail, I am googling daily for external interfaces to gmail.

Gtray is a windows program that at least notifies you when you've received new mail.

Another reason for imap support is offline archiving. There are many clients that can cache an imap server's mailboxes. Offline storage and searching are a powerful feature that gmail doesn't have yet. There must be a way...
