KDE, Unity, Gnome .... all wrong for me ...

Hi,
today I installed for the first time Mageia (3 Beta 2 KDE).
I thought I would be happy but didn't expect this: The preview of Documents you work on (and I do work often on five, six documents with Writer and Okular and Firefox) is just too small. It's as useless as in Unity. And the preview and the title only shows up when you already clicked on it. That leads to - compared to Mate, Gnome 2.3 and Microsoft 95 - W8 - a few thousands additional clicks within a month of work.
The new Gnome has this ugly fixed top menue bar which makes my huge screens became small ones ...
.
Any idea? Can you really use Mate with Mageia?
