It is the small patch which does style more flat and compact, in my opinion.
I also change the drawing of checked menu items with pixmap (see the screenshot).
my display resolution is 1024x768
to apply patch:
$ cd reinhardtstyle-0.8.2/reinhardt/
$ bzip2 -dc PATH_TO/patch-reinhardt-0.8.2.bz2 | patch -p0
$ make && sudo make install
...And I want to ask leinir to add this patch in the style as an optional possibility. Please :)
