Issue: Where is the steemit user interface (steemit UI) raw html editor option?

I don't know about the reasons why steemit decided to change the editor in the way it actually is but to be honest: I've seen better decisions from social media platforms in the past.

How can I embed videos in my posts now without posting my content directly to the steem blockchain (and without using the steemit UI)?

I hope this issue will be fixed asap.
