Direct Message: when I select a contact the potential left DM should be opened

[giomfo]

When I select a contact to start a DM the Element clients open the potential existing DM with this contact (if any). This point is good.

I suggest here going further:
if I don't have any DM in which this contact and I are joined, I would like the following mechanism:

• if I have received an invite for a DM from this contact -> I auto-join the DM (instead of creating a new one)
• else if I have a DM with this contact that they left -> I want to open it and invite again the contact when I send a new message (instead of creating a new one)
• else create a new DM

Note: the case where I'm in a DM in which the contact is invited, is already supported by the existing algorithm. The DM is correctly opened instead of creating a new one

If we agree to apply this new algorithm, we have to name the DM left by the other by the keeping their name (like we do when the contact is invited or joined). Currently this kind of DM is named : "Empty room (was Corey)"

We don't name the same left DM on mobile platform (Android / iOS)

We should take a decision

It should be "UserName (Left)"

Hey,

Thanks for this ticket.
We have users on our instances that have this issue, they don't see that someone left a direct message and send message to nobody (and they see only the problem later).
