But this is the whole beauty of pamac (or synaptic in other distros) that you browse and glance on pkgs, see their dependencies, read a description/summary, decide whether you want something or not, and finally click within a minute.
I don’t know how fast you (all) can type commands accurately, I obviously for building pamac or yaourt can, but why take 20’ and have to do clean up, when a click and seconds later you are running an installed pkg.
I know masochism runs high among linux/unix folk, but let us be a little logical. Browsing through packages and their descriptions with pacman is an exercise for your eyesight endurance of too much information for too little value.
And where the hell would you get a kernel installer/uninstaller like the one Manjaro had in Manjaro-Settings?
