The one feature I would really like to see in Musing.io is the ability to sort and filter questions. 

At the moment, it's still easy to navigate the questions based on when they were posted, but as the platform grows, it's going to need a better way for users to navigate these questions. So, improving the way that users can sort and filter questions can really help improve the platform's usability.

For example, I would like to be able to filter out answered questions, so I can only see the unanswered ones right away. Or sort questions using other criteria aside from tags. For example, view questions posted during a certain time period, in case I'm looking for a specific question.
