As I was mentioning to @eugen-b to avoid closing another then for not staying on topic. I am consider installing Moksha from Bodhi Linux which I was using during early in the last decade. Which was simply E17 setted up with rather sane defaults at the time.
Is there AUR support in Architect? I honestly don't recall as it has been around since I last messed with it on my laptop.
Yes I am aware I will have to learn Manjaro in much more detail, not to mention how to properly use pacman. And of course actually very likely hand editing configuration file as well.
Not only will I ask very many questions both here and on the Bodhi Forum, but heavily reading much if not most of each distros wikis.
