why no standard action for categories?

[Glen Mazza]

Hi Dave, reading your 2009 writeup on the Fauxcoly theme 
(http://rollerweblogger.org/roller/entry/more_about_the_theme) -- you 
list 4 standard actions besides custom: weblog, permalink, search, 
tagsindex, and have constructed Fauxcoly to be able to demonstrate each 
of those 4.

Question: why don't we have a standard action to display entries 
belonging to a certain category?  Is it because categories can be listed 
in a more traditional way or you just didn't have time to get to it when 
creating Fauxcoly?  I put in JIRA items 2021 and 2022 to add categories 
to gaurav and fauxcoly, I don't know if to get it done properly we could 
or should create a new action for it or if that would be redundant.

Regards,
Glen
