Please do not add superslicer to stable branch of manjaro.
Superslicer was move from aur to community. But the current community version is an alpha version, witch dose use the stable config directory (see FS#75133). This may result in a damage config and hours of fine-
tuing are lost.
Because of this I think Supersilcer should only add to manjaro, if the arch package use a stable version.
Furthermore it has also an aur package as optional dependency. So when superslicer will be added to manjaro superslicer-profiles should also been added to manjaro.
Their exist already a new stable superslicer package at the aur: superslicer-stable
