I would have preferred to stay with "GNU screen" over migrating to something else and re-learning everything all over again, but screen does not appear to be under active development, and for years I have been living with an annoying bug, where screen occasionally goes bonkers when I'm using "vim" to edit a text file. The only solution in this case is to quit screen and restart it, which is inconvenient.
I am assuming that tmux, which is actively developed, does not have this problem. Hopefully whatever other problems it has won't be too severe.

What happens when you run screen when another instance is already running? You get two screen instances, each running in a separate process. You can list all the screen instances with "screen -ls".
tmux
What happens when you run tmux when another instance is already running? You get two tmux instances, each running in a separate process. You can list all the tmux instances with "tmux ls". The tmux term for a tmux instance is "session".
In addition, you can work with sessions from inside tmux:
- CTRL-b :list-sessions
- Session and window preview/select tool: CTRL-b w
