I have been searching the net all afternoon looking for a way to get the comments heading back up.

I know that you have to add a comment when importing footage for it to be visible but when importing XD footage that wasn't possible.

Is there a way to enable comments?

any help would be greatly appreciated!

I'm not in front of MC right now, but don't you just click on the fast, a.k.a. hamburger, menu in the lower left corner of the bin and choose Headings? From that long list just choose Comments.

I think that should work.
