...which would begin with a much better "Feature Search" functionality in the theme and plugin depository! Right now the search categories are way to vague and don't include all desired options.

For example, I only want a theme that includes the excerpts() function and a sticky menu. Whilst with some these might be listed there's no comprehensive search option, like a long list of features with (let's say) 3 radio buttons to select: required, maybe (would use), not wanted feature.

If you don't know the name of a good theme you have a slim chance to find it. The same applies for plugins, where a few big ones dominate the search results. I tend to use a lot of lesser popular choices. Take the contact form (why isn't a basic contact form part of the WP core?): Contact Form 7 always comes up - despite it being a real problem with load speed. I use Caldera Forms because it does what I need.
