Musing might be one of the most compact, minimal and cool looking dapps among all the other ones based on steem blockchain. But it has some featured that are needed to be added or updated. Such as

• Markdown support. This could make the answers look more organized and formal than now.

-Reputation score. A rep score based on activity solely on musing. It will allow people to differentiate more authentic answers from authors.

-Seperate tabs for answerd and unanswerd queries. it discourage people from repeatedly answering..

-Saving incomplete answers as drafts before giving out.

-And the most important thing would be a cross checker tab that will show suggestion while someone asks a question like if the question was asked before. A simple search engine might do the trick.

And the other ones I wanted to mention is allready given in the other answers to this question.
