I suppose it is related to #148.
It would be great if newly composed emails could be previewed in the review screen, under the attachment list. This possibility should be offered in the configuration file rather than as a possible action within the dialog as one shouldn't have to press a specific key to display it. I assume most people would like to read their email one last time before sending it without having to open the editor again.
Any way to open a specific email in aerc from another program would be great. Something like: message://server/unique_id
See the Thunderlink add-on for Thunderbird, which does exactly that: https://addons.thunderbird.net/en-US/thunderbird/addon/thunderlink/
Ideally, it would be fantastic if one could select an email in aerc, send it to emacs via org-protocol, create, for example, a new TODO item related to the email, and then be able to open it directly by clicking on its link in emacs to have it displayed in aerc.
Please excuse me if this is already possible, but I haven't found a way to do it.
It would be very useful to be able to pass a message id/URL to aerc in order for it to open it directly, in particular for emacs org-mode integration (see an example for mutt there: https://upsilon.cc/~zack/blog/posts/2010/02/integrating_Mutt_with_Org-mode/
