It is one of the biggest things that steemit needs.
Search and sorting tools.

And when i have recommended them in specific, and how to implement them, it falls on deaf ears.

Really, a kid updated steemit to have a separate tab for posts and resteems... but, it was found that the back end couldn't support it. So, we never heard from it again.

Seriously, we should be able to go to someone's home page, and sort by tags shown in a tag cloud.
Want to see @papa-pepper 's crazy competition, should be easy, right? Just click... but no.

Further we should have private and public groups. Or lists of user, just like our follow list, but more useful, and shareable.
