Mine’s really simple; I just make the path bold and yellow:

What I like to do is change the colour depending on the machine I ssh into, e.g. make the path red on my Raspberry Pi.

To open an app launcher press Win+D, then type the name of a program you want to launch and press enter. Boom, you’re using Sway. Here are the default key bindings: https://wiki.garudalinux.org/en/sway-cheatsheet

Use gsettings:

gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita-dark' 

gsettings set org.gnome.desktop.interface color-scheme 'prefer-dark'

Windows 2000 looked amazing.

What kind of problems did you have?

I hope that when my current laptop dies, a somewhat libre and linux-friendly alternative with an ARM chipset will be on the market.

You might not even have to log out: Just change the user in the terminal: su - user2
