I use KDE, cos I like it. I run a lean cut down version and it suits me fine. I like the look and feel of KDE. Its easy to customise, has plenty of eye candy, if you want it and it does what I want... most of the time.
One thing irritated me. Firefox window size would re-set to the size when last closed. Sometimes opening to fill the entire screen, other times, it was small as a dialogue box.
In KDE you can control the size of any desktop window. Do:
KControl > Desktop > Window-Specific-Settings > New >
Window class (application type): Iceweasel
OK > Apply
For application Firefox (known as Iceweasel in Debian), it will open a normal window 700x900 in the top right hand corner of my screen. Great. Just what I wanted.
As I have a widescreen monitor, these settings work for me. You'll have to experiment to find out what's best for your hardware.
That's about it.
