Screen space.

I work in tech doing performance, memory management, and developer workflow tooling and automation for a large 3D Rendering/Creation tool.

Being able to throw a long setup doc, or a large class file on a 4k portrait monitor allows me to read things through with a ton of context and far less scrolling.

It’s also useful for putting two window tiles that have related content, or one is a reference content.

I currently have a tie-fighter monitor setup (2x4k portrait on either side of a ultrawide) and will put comms and email/calendar on my left monitor, core work in the center, and overflow reference/research on the right.

It’s less hectic for personal use, but I still use all the space.

4k monitors in portrait orientation are amazing for productivity. It’s a shame more people don’t do this

If you’re just looking for an engine that recommends you music based off your likes, the FOSS community could utilize the Music Genomoe Project to build a tool too do that based one a folder or Playlist of music provided to it. I would be surprised if there already wasn’t a FOSS tool to do that.
