The editor on "Dynamic Content" pages is pretty basic.

I have an editor of a page on my website who always asks me to embed a video for them.

Could this not be a button on the bar? it should be like the img button

Browse for upload, add a link (youtube?), embed code.

Also when saving to a database, the BODY field needs to be BLOB not TEXT, so that we can upload photo's rather than provide a link.
