Work continues on MATE.
The display settings received the following improvements:
– They show the output names as well as display names (This feature was recently added to Cinnamon 2.8).
– A new “Set as primary” button was added to set the selected monitor as primary (among other things this allows you to define where the mate-panel appears).
– The ultra-confusing “Make default” button was renamed “Apply system-wide” and given a tooltip to explain what it does (I’m personally in favor or removing it completely but I couldn’t reach consensus on this) :)
The power manager now also shows vendor and model information, similar to what was done for Cinnamon 2.8: http://segfault.linuxmint.com/2015/08/cinnamon-2-8-battery-vendormodel-info/
