Main using of PC is through Viewing through Monitor.
Doing professional work on PC require multy-monitor setups, 4k monitors, or even an extra monitor connected to a laptop.
Changing regularly all this setups is not easy as we do not have a monitor profile save and profile switcher, every time we have to manually go in display and change manual configuration.
things get worse if you use a laptop with different monitors or even the HDPI mate tweek switch present in a different window than display config one.
Hope someone will think on this for further MATE releases as this is quite important than other Mate New feature, or at least for me or for my opinion
