The new compose has at least 4 things that are broken for me:
1) When you hit "forward", it hides the subject box, even though the majority of the time when I hit forward I want to delete the "Fwd:" from the subject line. Especially when sending a form email. This resulted in a couple of embarrassing emails before I changed back to the old compose.
2) I often want to create a big list of emails that I want to review before hitting send. The new compose replaces each email address I type with the persons name! For a lot of people I do business with, I have both their business and personal email address. But now I can't tell which one I'm about to email. What the hell Google?
3) Attachments are now an object within the email. But often I want to forward something with an attachment, but clear out the text in the email. Well now when I do select-all, it deletes the attachment also.
4) The compose email doesn't cover my screen, even when I pop it out as its own window. When I'm drafting an email, I don't want to be able to see distractions. If other emails pop up while I'm editing it, that can make me lose my train of thought. Worse, there are no options that I can set to change this.
No can do. I refuse to turn shortcuts on because there are at least 2 (and maybe more I'm not aware of) ways to send the email I'm currently drafting. Command + Enter, or hitting shift, then enter.
I've learned from past email programs that's a recipe for disaster. Turn those two off and I'd gladly use keyboard shortcuts.
