Hi Ipstenu,
Thank you for joining-in.
I respect your opinion on this subject but I also disagree with it.
It is really simple to add a search criterion by version number since this information is available on WordPress Web site.
Yes this will penalize those plugins who have not been updated even if they do work with the newer version of WordPress but then again since we could search by plugin version number that should not represent a problem.
I am also persuaded that this new search field would also entice developer to update their plugin.
Thank you for your input.
Regards,
Ducktape
