I’ve moved from Ubuntu 14.04 LTS to Ubuntu-Mate 16.04 in the past 24 hours and I must say the development choices and layout/usability are great so far.
I only have one comment around the look/feel is concerning the login / lock screens. I know you can edit a number of parameters through the built in tools, but the default colour of the login/dialog box on these screens looks out of place. i.e grey/white light background (I do like all the other aspects/choice made in the default theme)
If you could set these boxes to inherit the setting (either colour or transparency) used on the main panel bar then this would make these screen much more integrated in to the look/feel of the OS ‘out of the box’.
(I’ve seen the posts around using the unity-greeter and have successfully tried this on a test VM - but having this sorted on the default greeter/lock screen would be great)
A massive thanks to the developers who have contributed to this release.
