Awesome! I made the jump as well a couple of weeks ago. Struggled hard with the installation because I was being dumb during some parts. When everything worked I got this nagging feeling that I must have forgot something or done something wrong, which is why after I was done with everything, I installed EndeavourOS. Still an arch distro and I went through the installation, so I’ll just pretend I’m one of the gang.
A similar thing is happening to me as well. My calendar looks weird and some app folders have squished together app symbols.
