It would be awesome if we could add a coloured bar or dot somewhere in line with a conversation rectangle (what appears in the list of all convos when opening the app), which matches whatever you set their accent colour too - especially useful if you have a contact picture which obscures that colour already.

It may be nice to have the ability to change how all these conversations display or are listed together, like bubbles or a grid size of one's choosing, instead of just a vertical list sort of view.
