Can you be more specific as to how you want it to work compared to how it works now? (It would be useful feedback for somebody building a browser extension or to those at Google.)
Well, for starters, I don't like that they have designed the new compose like a larger chat window. I prefer the compose not be a modal or window. I want my formatting above my message, right under the subject line. Perhaps, when compose is click a compose tab activates with full view on page compose form.
...and if they want improve auto save, give me a history diff every time it auto saves just incase I want to revert to previous version. This would be helpful for those times auto save kicks in just after you deleted a sentence or paragraph you're rethinking. Once message is sent, edit history can be removed.
The biggest annoyance I have is that there is no way to do that for Reply. Why should Reply be different from Compose? They're both just sending an email.
The whole thing is poorly thought through. Countless details seem off.
I'm thinking of going back to Thunderbird and using that for the client (while keeping the Gmail account as the server). Much saner experience. I agree the new compose is all kinds of wrong.
Depressing. Only 14 people agree with me. I still hope someone builds an extension. Fingers crossed. This isn't just about the new compose. As @gruseom said... countless details seem off.
Basically you launch it, it jumps straight to the blank compose window (nothing else), and closes when you hit send. That's it.
I try use it for the times when I don't want to see my email, but need to email something.
