You shouldn't need a plugin to click on items in your list and view
individual posts. Just make the items hyperlink to the permalink pages
for each post. Take a look at the permalinks in the default flavour.

I think your plugin needs to do two things (maybe two different
plugins):

1. Reverse the sort order of items, maybe a cb_filelist plugin.

2. Make it so that on index pages (such as the front page) only
the title of each item is displayed and not the full contents (I think
this is what you want?).

I think there are a lot of ways to achieve 2. You could do it easily by
using one flavour for the index pages and having that flavour hyperlink
to another flavour for the permalink pages. Probably there would be much
shared code between the two flavours, differing only in the story
template, so one flavour could consist mostly of symlinks to the other
flavour's files but with its own story file. I've done this before and
it works, but I feels a little inelegant.

It might be more elegant to write a plugin. This could be a cb_story
plugin that changes the 'body' field of a story to an empty string if
the request is for an index view. This would be similar to the readmore
plugin:

Or perhaps it could be a cb_entryparser plugin that changes the value of
'template_name' in the entrydata dict if the request is for an index
view, using a different story template for index views and for permalink
pages. See:

http://pyblosxom.sourceforge.net/1.5/dev_writing_plugins.html#writing-an-entryparser

I'm a plugin-writing newbie, so my suggestions might not be the best or
easiest way of doing things. Will would know better.
