RSS feed reader

Can anyone suggest an RSS feed reader that has the following features:

lean
displays messages in plain text
organises each feed as a separate database file
can save selected messages to user defined database files
searchable databases
filterable databases
can launch selected message in external browser

RSSOwl looked promising until I discovered that it uses a single
database file for EVERYTHING, including my saved messages (why ???!!!)

I'm currently using Opera 9.64. Its RSS client is OK, but Opera
organises its feeds by date rather than by group. That is, there is a
separate directory for each day of the month rather than a separate
directory for each feed. These directories contain MBS files, with
each MBS file containing a single message which can be from any feed.
I would prefer a database where each MBS file concatenates all the
messages in a particular feed, in the same way that my email client
(Eudora) and newsreader (Forte Agent) do. Furthermore, Opera uses a
single index file for the entire database -- I would prefer separate
indexes for each feed, just like Eudora and Agent.

BTW, I am reticent to upgrade Opera. The last time I did this I was
hit with a resource leak problem. Opera's developers have stated that
they do not test Opera under Windows 98 except to confirm that it
launches and runs.
