It shows contact list and conversations in a single window that does not fit in the screen, unless one uses the scaling option, but then it is so small that it is very painful to read.
I installed dino using “sudo apt install dino-im” so it is from the standard repo, version is 0.2.0-3. Are you suggesting to install the version indicated in this post? Would that version allow conversations in separate windows? Or are you referring to a different version?
I added the octarine repo as suggested but apt update gives an error:
Repo https://repo.pureos.net/pureos octarine Release does not have a release file.
Note: I see people looking for voice calls, I have no interest in that (I use regular voice calls, they work fine on L5, I have no use of a US/Canada phone number as I don’t live there).
