Customize the wallpaper per conversation

[prowell1984]

Hi there,

Please consider adding a functionality of wallpaper customization per chat (as it is on the mobile app). It would be amazing if it could be in sync with the phone. If not, the simplified version would be the ability to set it per chat manually. This is very helpful feature that let's you keep track of the multiple groups and avoid leaking information.

Have a great day.
Kamil.
