Sadly I can’t recommand pop-os. In 2 years, the updates broke twice on me.

The resolutions where simple enough if you can use the command line to run sudo apt update, sudo apt upgrade. But the GUI shop updater just crashed on me without the apt error message visible.

It is a nice distro overall with which you can even try tiled windows without commiting to it.

-> pop-os is nice but it may break from times to times. So if (like me or most dev) you are ok with the CLI and just a bit of fixes from times to times then go for it. But if you are affraid of the CLI or never want to fix anything, then some other distro may be a better choice.

I know simple fossify apps are appreciated by the comminity. I have yet to try them. I like Etar as a calendar. It is also on FDroid

Where can I learn what each colors means? Is it buried in man htop somewhere? Or in a website?
