Threading is broken for recipients who read mail with GMail/Outlook webmail/maybe others

Of course, the easiest solution would be to use a fixed unchangeable subject for any message sent by DC in a 1-on-1 chat. This shall easily solve both issues above. I didn’t put much thought in it, so it might have also some serious flaws.

The flaw is that we have to decide on one subject for everyone and Re: <previous subject> is maybe the subject that normal email users use the most (just reply to the last email).

BTW you can reply to another message by swiping right on this message, this will also change the subject.

Other idea: Maybe now, with all these email-compat things being done, (or, in some months when all these some of the ongoing projects are settled) is the time to make the subject user-changeable?

• I think on Android we can put this into the overflow menu and remove View profile, Add attachment and Archive chat because all of these can be accessed in other ways and I don’t think I personally ever used them.
• if the sender set a custom subject using DC, we should probably also show it for the receiver using DC. Maybe just introduce another custom header Chat-Show-Subject.
