Unfortunately that would lead to many great apps not getting proper attention. Things such as a downloads counter would simply promote the highest rated ones, preventing you from even considering newer alternatives.

I would prefer to have more options to filter by time of release. Such as past month, past 6 months, and past year. That would filter out unmaintained apps altogether, even though there are many that still work well years after release.

Another one would be search operators, or simply a better string matching algorithm, as I keep searching for apps that I know the name of, but make some typo, and they don't appear. Wonder what that is about.
