in this one, documents is on the first tab. i have to say that i much prefer 
the look in #4, even if it would mean adding a scrollbar... hm.

and again here, i wonder if it would look better with Sessions and System in 
separate colums? i suppose that means an even strong bias towards headings in 
their own columns, like in shot 9:

very nice

something that occured to me while looking at this is that the right aligned 
headers only really "work" visually if there is a single column. in multi-
column, i bet they'd look a lot nicer centered (and in single column, they 
probably look nicer right aligned)

woah =)

you should be able to just set the width on the item, and have the item itself 
(or, rather, the delegate .. most of that code is in libs/plasma/delegate.* 
these days) handle squeezing it's painting in properly.

as for determining the width, QFontMetrics can tell you the width of a 
character, so something like:

QFontMetrics fm(font());
int maxWidth = fm.width('m') * maxNumberOfCharacters;

in kdeplasma-addons/applets/lancelot

the trick is to paint only the number of letters that will fit (Qt does that 
for you) and then paint over it a gradient ...

the above are my comments.. great work so far, i look forward to reviewing the 
cleaned up patch and getting this into svn for 4.2 =)
