CSS Online Editor and Attributes
It's an obvious feature to propose, but having an online CSS editor and realtime preview would really differentiate Zoho Wiki from the competition.
In the mean time, is there documentation of the current default Wiki CSS (see http://help.zoho.com/portal/en/community?ftid=2266000000027654) that describes what each attribute controls? Or at least the major attributes like page size, background, menu colors, etc?
