One of the most annoying things about installing Manjaro, for me personally, has always been linked to my installation choosing the latest kernel for me rather than an LTS stable kernel. By default the installation media throws you on to the experimental path rather than stable. I don’t know why it happens but the default for any new user should be an LTS kernel. So I hope this starter of yours addresses that issue. (Obviously I know how to change kernels - but this might be an issue for newcomers.)
By the way - love the screen shots - clean and easy to read.
