hi!

regarding the description text, i had the problem that as a summary, always the description showed up.
now, this is fixed and also html does work in summary and in description view!

to enable html in summary view: search for the following line(around 217):

$summary = $this->getVar('summary');
right BEFORE this line, insert this one:

$this->initVar('dohtml', XOBJ_DTYPE_INT, 1); //allow html

to enable html in description view: search for the following line(around 236):

$down['description'] = $this->getVar('description'); //no html
do not remove it, even when it says no html!
now, right BEFORE this line, insert this one:

$this->initVar('dohtml', XOBJ_DTYPE_INT, 1); //allow html

now, the description should show up, and also html should work in summary and description view

ps: in admin category configs, you should check "allow html" and maybe disable auto linebreaking. there might be some confusion regarding the german version since it says "disallow html" when it actually means "allow html", as all the other code devoted options are negated.
