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.

When we add a COMMENT there is a DATE attached. If we go back to the comment and have to make follow up notes, the DATE changes. It should NOT change. We need to see ORIGINAL comment dates. We need the option to keep the ORIGINAL comment date and make follow up comments inside the original without changing the DATE

I hope in the highlight comment feature, that the mouse pointer remains in a circular shape even above normal texts .. This will give more freedom to select the desired text .. because some texts are thorny and difficult to define with the text cursor for the mouse ..

In a long document with multiple comments, the name of the comment author, and date of the comment, clutters up the actual comments and makes them difficult to read. It would be much cleaner if there were an option to hide the name of the comment author and date of the comment in the comments panel. Thank you

This version is unusable due to unstable flickering, with slowed down response to page scrolling, freezing search, or black rectangular shapes covering the whole page or partially the content.
At this level, there are no ideas to be suggested since the very basic functions are affected

i use the pen from the comment tools to write notes, but it is difficult to write with it because it is not smooth, making the writing process very slow

Fix this by adding an outline to the fill color so that it is still visible when the highlight color is gray

I'd like to see one be able to choose what comments are to be printed in a summary.
For instance I do not need a report on every highlighting.
Highlighting with comments, and comment bubbles themselves yes.

I'd like to see a line to the reference number in the margin if one selected this time of summary. I do not like the characters covered by the numbers.

[Measuring tool] Please add the ability to change the color of dimension text, similar to the ability to change the color of the dimension leaders & arrows.

You are not able to keep a tool selected any longer. If you use it once, then it reverts back to the cursor. Stamps, highlighter, comments, all of them. This had been a feature in Acrobat since I can remember and all of a sudden they removed it. WHY? Bring it back. There are several other people on here complaining of the same thing but if they don't respond, they say the issue is resolved. It is not in any way "resolved". Please bring back asap.

I would like to have the date show up in the sticky note.

Currently, only the Author and time show up.

Why not have all three? It would be very helpful, as I currently have to key in today's date every time I enter an order or if I reply to the sticky note.
