I needs to connects to multiple servers at the same time, and tmux sessions shouldn't be stacked. How can I do that without tabs?

If you have 2 tmux servers with different hotkeys you can totally nest them safely. I have a different hotkey prefix for my machine and then leave the default for servers. Works great!

Use multiple panes and/or windows? It's a terminal multiplexer, each panes is a separate terminal, just like tabs.
