You’re right. I wasn’t familiar with rawtherapee but just seeing that home page immediately clued me into the fact that it was some kind of image program. Didn’t even need to read a single word.
Come to think of it, there have been a number of times where I’ve wondered about what a foss project does/looks like and I think a single screenshot would’ve just been a big help in understanding how it behaves.
Does Incus allow you to use a VM with a GUI? One thing that’s nice about Proxmox is I have one VM with a very basic lxqt setup for when I need that, and I can either use remote-viewer + the spice protocol to access it or access it through the Proxmox web ui. That’s been very handy.
