Comment UI was better in former version
Each comment in the column on the right hast to be opened to be checked with done (check mark). But then the answer-field is opening and the answering field of the former comment will be closed. When the checkmark is not set, the comment is always shifting a bit up. That makes a work with 500 corrections really bumpy/uneasy.
The size of each comment is also too big. In the former version there were 17 comments on one screen, now there are just 9 comments!
Make one comment without opening and smaller and more clearly arranged without moving!!
In the CS6 version of Acrobat Pro it was much better!!!!
For those of you who would like to have the "No Fill" option reimplemented, you please vote for it here: https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/suggestions/33141349-draw-shapes-add-a-no-fill-option
Also, I've written an article about the "No Fill" option and how it can still be accomplished using the Properties Bar: http://documentgeek.blogspot.com/2018/06/how-to-make-pdf-drawing-markup-with-no.html
Adobe added a keyboard shortcut for marking a comment as checked : Shift + K.
There is also a third party tool that will mark a comment as checked. That way, you can add it to your Quick Tools and so you always have the ability to mark comments as checked, even without the Comments Pane open. The added benefit of the third party tool is that you can mark multiple comments as checked all at once. I wrote about it here:

yep, you need to sort out the no fill option, dumb idea on every level taking it out
No fill transparency in the new tools. Step backwards. Please implement.
Why can you no longer select "no fill color" in the colour picker? It's annoying that you have to open the properties bar each and every time (but at least that still works)
Stupid to not include all options (no fill color) in properties.
I am annoyed that the shapes can no longer be hollow! Please revert back in a future update. Thanks!
YES! I still use Acrobat 9 every day because of the better UI for commenting! http://documentgeek.blogspot.com/2015/04/why-i-run-four-different-versions-of.html
I hate your new version, and loved the older version. The graphics and tool bar are horrible in this new version. It is like you went backwards.
