Eudora 8.0.0b1 has been released.

This is the open-source package of the Thunderbird engine with the Penelope plug-in to add various Eudora features onto Thunderbird. I (like many others) have tried several times to switch from Qualcomm Eudora 6 to a different mail client with better IMAP support. I have tried Thunderbird (more than once), Mail.app (more than once), and Thunderbird+Penelope, but none of them were acceptable replacements for Eudora 6. Both Thunderbird and Mail.app are heavily mouse driven, while Eudora does an excellent job (especially with function keys and the toolbar) of supporting keyboard control.

It looks decent, but I think it was a bad idea to use "Eudora.app" and the same icon as Eudora 6. Once they have a release version this might make sense, but for now I run both Eudoras, meaning I had to change the name to avoid a conflict, and I can only tell them apart when Command-tabbing because the new Eudora has no actual icon -- just a green unread-messages badge over a missing icon. So telling them apart isn't difficult right now. Perhaps they can flip the Eudora icon left-to-right, and we could remember that the pencil pointing down-left is Qualcomm and pointing down-right is Thunderbird-based.

Now I have to try it out and figure out what's missing, and file bug reports.

Toolbar customization seems incomplete -- I can't yet figure out how to remove the Print button from the toolbar, although presumably this is just my own ignorance.
