Suggestions for this feature:
1. Add read out loud to the toolbar for easier access, including pause and play options.The read out loud feature is currently very inaccessible from the "view" drop down menu.
2. Allow user to choose where to start reading and stop reading by highlighting text, rather than the limited ability to only read full pages / the entire document
3. Upgrade voice - please consider adding a more adaptive voice to the program for read out loud. the system default is not pleasant for listening and we know the technology exists to have more advanced AI voices such as Google Assistant, Siri, and Alexa integrated into software.
4. Echoing another user - definitely highlight words / phrases being read aloud.

These suggestions are already standard features in many of my digital textbooks; however, the majority of my reading as a student consists of PDFs from scientific journals. As a college student with a visual impairment, I would really like to see these features be improved to meet today's technological standards and made more accessible to individuals with disabilities. I am planning on completing a five-year graduate program, and will be eagerly waiting for these improvements to be made.

For all of the machines in my Win 10 2004 test group, the Reader plugin for IE (AcroPDF64.dll) has lost the ability to start the print dialog, either from the handy button in the border UI, the drop down menu, or Ctrl+P. In all cases nothing happens. There are a variety of versions on the affected machines but most of them are quite current (20.9.20063 and ...65). The problem is restricted to IE (11 I have no other versions to check) and the new windows 10 2004 feature build.
If you're interested in any other data I can provide on the issue feel free to let me know.

After opening Acrobat Reader DC (in a windowed mode, not in tabbed), it, for some mysterious reason, switches off the Windows 10 Explorer setting for windows to cast shadows. It results in focused folder windows becoming visually borderless, making it very difficult to work with them.
The problem was described here for Acrobat DC:
https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/suggestions/38822896-bug-shadows-disappear-on-windows-10-explorer-wind
but it fully (and even more irritably) applies to Acrobat Reader DC, too.

It seems that for some reason, Acrobat Reader changes (switches off) each time the inherent Windows setting which can be found in System > Visual Effects tab > Show shadows under windows checkbox.

The problem persist already for a long time, please fix it!

Since using Adobe Reader DC for PC, the last few updates have only increased the number of clicks required to do basic tasks. When saving a document, with either the CTRL + S key press or selecting Save from the file tree, there doesn't seem to be any necessity to have the window attached pop up. It's a similar feature to Office programs now, and really only makes the process take longer. Clicking on Choose a Different Folder just brings up the same save options we had in the past. This just creates more steps and wastes time.

To be clear, this dialogue appears when I press SAVE or CTRL S, not when I click on Save As.

I have to work with PDFs a lot and I have to deal with them via browser. For the past years I haven't had any problems with using the browser PDF-viewer, but as of recently the option to do a quick google search in a new tab when highlighting text within a document and right-clicking on it is no longer available. There is 'copy', 'print', 'rotate', 'save as' but not the 'search the web for [highlighted text]' which was so very helpful and useful for me. Please, consider making it available again since I can hardly imagine how anyone would benefit from removing this feature.

I need to read a PDF while using others apps at the SAME TIME; Reading the documentation of the other program from a PDF file.

I don't need toolbars. I dont' need status bars. I don't need menu bars.

I can press ctrl-f If I want to search for something, I can press ctrl-p if I want to print the document. I don't need a buttons or search bars for those to be constantly visible.

If I need to use ANY other functionality, I can right-click and all that functionality could be put into that right-click menu.

I ONLY WANT TO SEE THE CONTENT OF THE PDF!

So, you already have a "read mode". But you have failed it miserably; This read mode makes the acrobat reader go full screen, which is totally unusable; I need to be able to multitask, I need to see the documentation which is inside the PDF and to be able to use my other programs AT THE SAME TIME.

This is probably one of the most common use cases for PDF viewer and you fail it miserably. Full screen "read mode" hides my other program. and on windowed mode acrobat reader wastes one third of my window space for unnecessary UI bloat.

I have problem when PDF document is stored at network drive and my notebook has temporary problem with WiFi. Or when notebook is suspended and later resumed, network drive is not accessible for some time (I have to reconnect it manually). In such cases I see many blank pages in PDF file that was opened in the past (new pages are not read from the file). I have to close document and open it again. That is not nice and I believe that "refresh/reload" function will fix this problem. It is possible to find similar requests in the forums on Internet.

Other use is for users who create their own PDF files, like printing to PDF file, so PDF file is changing on their drive.
