duc, aur: it indexes file sizes of all your files and lets you browse it with a ncurses ui, for me that lives in the terminal this is a very handy tool for finding where all my disk space went.

It's a collection of photographs I find wallpaper-worthy with a GNOME wallpaper configuration file that changes the wallpaper based on the time of day each picture was taken.
One of my favorite AUR packages is noise-suppression-for-voice-git. It can be used as a pipewire plugin and can filter noise from sinks and sources, such as a microphone for example. Similar to the popular noisetorch, it's also based on RNNoise. However, noisetorch can't be loaded via a pipewire drop-in config and thus has to be started manually or via a systemd unit, and also performs an update check everytime it's started. Thus noise-suppression-for-voice offers a cleaner solution IMO: https://github.com/werman/noise-suppression-for-voice#pipewire
