Yes it is an Arch base. Not sure on the apparmor stuff and snap is basically banned from the Arch repos so it's relegated to the AUR which makes it a pain.
Yeah that's certainly annoying but still relying on SDDM to solve this. There is a movement to see if we can import SDDM into the KDE umbrella but it's a bit stalled at the moment.
Harald, the main architect behind it is already running it as his daily driver. Many others (myself included) are already testing it in VMs and on spare hardware with only very minor papercut issues to be resolved.
Yeah, looks to be an instance specific bug I guess. Hopefully it can get addressed soon. I think the thumbnail helps with drawing people's attention to posts.
I gotta say and it feels weird to but I'm happy Arch are spending a bit longer testing these days. When I used to run it updates just felt rushed into the repo so Arch got it first.
I have, but I also learned a few new things about column from this video, nice!
