Is it possible to just search “driver” or “kernel” to open the driver and kernel manager? We only need to search “install” to open Pamac. How about doing it in the Gnome Settings? Manjaro KDE does it in the KDE Settings.
It is really unintuitive to search “Manjaro Settings” for installing new drivers and kernel.
MSM and MHWD are rewritten as we speak by @LordTermor and will cover/fix some of the inconsistencies that the current ones have.
The integration in KDE Plasma is much simpler than in Gnome, because of the way Gnome Settings is made.
