Worth a look
I keep Linux Mint MATE going and updated even though I've happily settled on Debian Stretch MATE now. MATE 1.18.0 in Mint 18.3 has managed to introduce some problems into itself, both cosmetic artefacts and functional shortfalls. Because of the general flexibility, open nature and multi-layer nature of Linux and MATE, I've been able to work around these but it was annoying for a while.
I'll have a look at this latest version of MATE as implemented by Ubuntu to see how it behaves and if it offers any advantages over the Mint implementation. After all, the only cost is some time on a wet weekend and the occasional blood pressure spike when I see how they've changed my favourite feature or theme.
