I wonder whether Linux Mint will follow suit?

Mine is simple (inspired by Kali Linux, if that’s even correct)
PS1='\[\033[0;32m\]┌──[\t] (\u@\h)-[\w]\n└─$ \[\033[0m\]'

Very helpful command it was for those, whose modem had to be rebooted daily back in the day: Have a cron-job open the tray, which in turn was placed strategically so that it would hit the reset button of the modem, then close the tray. And voilà; automatic reboot of the modem. Robotics at its finest!

Apart from fzf that helps me find recently used commands and also files and directories easily, I also use tldr that gives you a simple cheat sheet for every command and very often saves you trawling through endless man pages.

I use external hard drives. Two of them, and they get rsynced every time something changes, so there’s a copy if one drive should fail. Once a month, I encrypt the whole shebang with gpg and send it off into an AWS bucket.

Terminator for me. It has tiles and tabs and does everything I need.
