There's a human-factors issue with the "Save Drafts" functionality. It presents an interstitial (intermediate) message that warns users that it will not save attachments, polls or certain options. The message ALWAYS appears, even when none of those things are in the message. So the message is irrelevant.
This is a human-factors issue because a user expects "save" to simply save. He doesn't expect an interstitial and may walk away or page away, then hits a loginwall when he tries to recover. Worse, this is most likely to happen on complex, thoughtful messages on which the user has spent some time, a loss to the community and a frustration to the user.
The answer is get rid of the interstitial, at least for messages that don't have polls, attachments or options. Discussion and several proposals here
- don't do interstitial (or bouncethrough) if no attachment/poll/option detected
- place the warning inline with an asterisk on the button
