It tries to kill the unnecessary overused task-bar and try new ways of
working.
That would be the taskbar that's used in hundreds of millions of desktops,
the world over and is the basis for collating shortcuts and various other
information feeds.
Sorry - unnecessary and overused are words that just don't apply.
However, we are of course arguing about whether slip on shoes are better than
laceups. I did nothing more than express an opinion. And my opinion is that
these desktops are poor and unintuitive. I do not want to have to learn how
to use my computer all over again, it's a waste of time. Nor do I want a
touchscreen based UI on my non-touch screen based computer.
I'm happy with Mate and KDE is is just about the best desktop I've ever used.
But, whatever gets you through the night...
