These dotfiles are for my current Arch Linux installation on my ThinkPad T550. I am using i3-gaps in combination with a GNOME session (follow the guide here. This allows me to configure things like wifi, bluetooth and my touchpad with minimal configuration.
I manage my dotfiles with dotfiles.
I use i3blocks as my status bar. By defining signals in the config and using custom scripts that send signals whenever the volume or brightness is changed, the bar can update instantly.
For music, I use mpd with ncmpcpp as the frontend.
For my mail, I use neomutt. You can find an excellent wizard here.
