- How is vim + tmux compatibility these days? Particularly with regard to powerline, etc. types of plugins? Is there a good resource that helps one set this up from scratch?
- I find that SSH times out / disconnects if unused but only on my mac, not on my linux machine. I don't have any of the configs described here on either machine, so I'm not sure why one disconnects and one doesn't - is there some out-of-the box macOS default that needs to be changed, or is it some arcane battery optimization macOS feature that's killing the SSH sessions?
I find I like having "set-option -g mouse on" in ~/.tmux.conf so that mousewheel scrolling feels more natural (like it does in a local terminal).

This one is a little tricky - it partly depends on the default settings of the remote sshd_config for sending KeepAlive pings (changed Debian 10 to 11, e.g) and what your local vendor-compiled ssh_config defaults look like. In general, to just solve the problem add this to your macOS ~/.ssh/config at the bottom/end:
Host *
TCPKeepAlive yes
ServerAliveInterval 300
TCPKeepAlive is what it sounds like, it's the L3 level tweak. ServerAliveInterval is a higher level ping-pong on the SSH session itself; kind of overkill to have both configured, but it Just Works(tm) for most people to have them set on their client. You can look these up in the man pages (ssh_config, sshd_config) and discover even more tweakable options than just these two I presented - some you can set server side, some client side, some both.
Side note: bash has an envvar `TMOUT` -- if that's set, bash will auto-logout if you idle in a shell. It's usually not set on most Linux server installs, just be aware it exists and is a thing to look for if you're debugging some day.
