I would love to see Photoshop in browser as a self-hostable option. I have many tools setup on my LAN and slowly been porting applications over to my local server so I can access all my applications on all my devices.
It's basically a whole developer suite with remote processing. I could do AI training on my cellphone with this setup if I wanted.
I've been working on a DIY spotify clone for a media player.
It makes it really convenient having all my files on a central server, so I'm not juggling drives, and copying over data.
As well, it's automatically backed up weekly so it's always safe.
Works well for someone always on the go :)
