Eucalyptus' filters window is now 99% operational, and the settings dialog is getting very near completion. Still need the viewers/mailcap dialog and some mail transfer progress windows, and we'll be right as rain. Eucalyptus is coming very close to being a usable mailer!!! Wheee!
What's left after that is what I'll just call "flash": viewing attachments (esp. images) via internal (or see next) viewer, and (what seems the coolest to me) Bonobo, so anyone can use their favorite text editor to compose messages, as well as using the appropriate program to view attachments. (Do any editors support Bonobo yet? No? Say it isn't so! Guess I'll have to port my favorite over from the Amiga ;)
