hello guys, i think that a user friendly OS must guide the user to do the basic things
for example, when you first boot the first thing the OS must do is to ask the user in the CLEAREST way possible to choose the language (with icons, images etc), then the keyboard layout etc
then it could have a little basic guide of how to install things, what is pamac, show the basic features of the DE etc
also it needs when you select the language on the liveiso the first thing that appears is a english manjaro hello, when you open calamares and select the language a lot of stuff isn't translated and when i first boot up you need to install additional language packages, but the OS doesn't say that you need to do that in the first boot, it isn't obvious to a new user that they need to install language packages they might think that is a problem with firefox or whatever application they are using.
i also suggest creating a newbie tutorial in the manjaro hello in the respective languages and DEs, so they can learn the basics of the DE and linux and how the OS works, like how to install programs, how to customize the interface etc.
also with firefox, i think it would be better to disable the titlebar by default, the setting is a little hard to find on firefox.
basically adjusting those little details that makes a polished experience.
