At the beginning I like that the comment bar shows every comment on a page as an individual element, which I find to be very useful for long, distinctive comments. However it gets less handy when it comes to minor comments, such as highlighting important words on a page. Each word highlighted, or to say, each mark you’ve made on that page will be shown as an individual comment under the comment section of the page, making the comment list unnecessarily long. I think it would be nice to be able to group or merge some comments together.

i hate that you changed everything, especially took away the tools that provided a box with an arrow that put text insside, and the eraser

Allow custom position and size for comments bar to allow multiscreen editing (InDesign on one screen with comments, Acrobat document on other screen).

Adobe acrobat needs British English (as opposed to American English)

I am sick of seeing the red line for the following obvious reasons
behavIOUR
colOUR
SummarISE
etc

American English is not the standard, its a variation on the theme.
Please add British English to the program

Include a highlighting tool that doesn't show up as a comment. We use the highlighter to indicate values that have been reviewed, but it makes the comment summary and the comment window very cluttered. It would be nice if we could either exclude highlighting from the comment window or generated comment summary or have a separate tool.

Add in Stamp (of an actual stamp that been created) shortcut to the tool bar where you can set its default properties (Size etc opacity) for when that instance has been added to a page, and then what happens next ie is it pinned or does it revert. This gives flexibility for handling large number of document or just a small amount. Being able to save a couple of clicks everytime would be a big help and something I think would improve a lot of peoples work flows. Thank you. Gabi

at the same location from previous page when selecting a text block and try to highlight it, switches to previously highlighted text in previous page and change the whole text block to that previous text.
if ( Text in page 2) highlighted it will change to (text in page 1) in order to reverse this need to change the page and back again until it works
also, the selected text disappear after finishing from selecting along with the options that appears after selection.

Previous versions of Acrobat would hide comments when their status changed and no longer matched the current filter. Can we bring this back? It makes doing corrections so much easier.

Highlight feature not working properly. It selects a large chunk of the page to highlight.

According to the PDF spec it's possible to create coloured annotations which are non-RGB. However, when you create i.e. a CMYK annotation, Acrobat takes the first three values and interprets them as RGB. I.e. [1 0 0 0] results in red instead of cyan, see attached example.
Interestingly, Preflight validates the document so somewhere in the company the knowledge is available.
The goal should be that annotations are displayed correctly independent of how many colour channels are there.

The bookmark tool only allows you to change the colourt of the text and not the background colour.

It would be useful to be able to have say yellow tabs with black text

It would be useful to have simple coloured bookmarks which operate like coloured tabs in level arch files. These can mark out a particular top eg jet engine fan blade orders

In addition these can be nested sorted/arranged if necessary with secondary labels/hidden text which appears when you hover over them.

Buy a dictionary or, better yet, use your iPad to lookup the meaning of ANY. On your website it says DC pro WORKS ON ANY DEVICE.

There are millions of these new things called tablets sold every year (for the last 10 years) Send someone from marketing back to elementary school to learn about ANY. When they get to law school, attend the class on false and misleading. REALLY disappointed with Adobe.

For power users and quick use, add an option to pin comment bar and or other toolbars to the top.

It is possible to highlight text, but not enter anything in the comment box (no need to in my case). Eventually, the comment box locks in place and you can't close it.
Workaround: save and close the document and re-open it.

-It would be really great if you added a tool or section in the program to show a list of all highlighted areas with the ability to search and select between them.
And also another section to do these for comments.
-The highlight tool can work in bookmark panel.
