list VS tmux-cpu

There are more that I want to look at, but didn't have time yet. The 3 above are super useful.

In this section, we address configuring ~/.tmux.conf. There is a repository on Github that lists Tmux Plugins. But to use them, there's one particular plugin that you need: TPM. TPM is the Tmux Plugin Manager.

tmux-plugins/tmux-cpu - While it is easy to view CPU load averages by looking in the header of htop or just typing the uptime command, tmux does have the ability to show this information as well in the status bar. But tmux-cpu provides a more comprehensible display of this information including color levels. It also displays GPU information, which I'm not sure if that will matter on a Raspberry Pi unless it can report the status of the embedded graphics chip. This plugin does have some optional requirements that should be installed such as iostat and sar to get accurate CPU percentages, free to obtain system RAM status, and lm-sensors to find CPU temperature. Since iostat and sar are part of the sysstat package, free should already be installed as one of the core applications, and the closes thing to a mention of lm-sensors is a community repo package called i2c-tools, there are going to be some things to install. Oh, and probably something VERY IMPORTANT, install the raspberrypi-firmware-tools package. Because of this point, I had to go back and add another section. (There is sooo going to be a Mk3 later.)
