Who need GUI apps when you can do these things on CLI:

• view image: imcat my-image.png
• watch video, even YouTube: mpv --vo=tct "https://youtube.com/watch?v=BBJa32lCaaY"
• browse the web using modern Firefox engine: browsh
• listen to your Spotify playlists: spt play --name "Your Playlist" --playlist --random

and perhaps many more I’m not currently aware of…
