As someone new to Manjaro I would like to say thanks to the devs for making it the easiest version of Linux I have tried thus far to get things working. Having said that, there is one thing that I have seen which could be made easier for Linux noobs coming to the system. That is the initial updating routine with pacman.
While I suspect that there is already a way around this in the CLI, it was not apparent to me when I first booted up (I am a Windows user trying out Manjaro so what seems obvious to an experienced Linux user will probably not be so for me). I was able to find a guide on things to do when I first booted which took me to the whole pacman command line thing.
I just think that for new users, Windows users especially (who mostly will have never even used a text based command, let alone have an understanding of Linux script) it would be more user friendly to add the script to an on desktop shortcut marked 'Run this for initial update' or words to this effect.
