The Comment Panel was much better in Adobe Acrobat 9, that is the whole reason I didn't want to go to DC, but now I don't have a choice because of security. I think you should be able to move the panel to the bottom like in Adobe Acrobat 9. Also this version, as soon as you click on it, it takes up 2" for one comment, that's just crazy. Also, the filter function doesn't hold, I have in the past in Acrobat 9, selected to show None so only my comments that haven't finished show up. But in this version it doesn't hold, because as soon as I do the next comment, it stays on the page, when it should disappear. Very disappointed that we have lost features, not gained them.
