I sometimes get really frustrated when searchning for plugins. I just searched for "tag posts widget" and the first plugin says:
Last Updated: 976 days ago
Requires WordPress Version: 2.8 or higher
Compatible up to: 3.0.5
It has 5 stars.
Could be filter by date last updated and / or compatibility - so we can chose to only see plugins updated in the last 6 months that are compatible above a specified version?
This should make finding stable plugins much easier for all.
