A fully functional spell checker is necessary for Acrobat DC (17.009).

Frequently I get documents requiring proof-reading and the only option is to export as a DOCX, run a spell checker there and, for every error, go back to DC and either comment the error or correct it myself. Not ideal, to say the least.

Such functionality would also provide useful features. For example, to check French text has the correct accents or, even, being able to "translate" from US English to British English

Make it possible to set a default color in the menu:
Preferences > Content Editing

in addition to the already supported settings for font and its size.

You are missing a most basic editing feature: The ability to display additions or deletes to text in a pdf, as in Word's "Track Changes". How does a client see my edits to their document? Really! Will this be rectified?

The online version of Adobe Pro DC needs to have an edit function for existing PDFs. Especially ones that were created in the desktop version of Pro DC. You are unable to continue working on a PDF that you created on the desktop, but need to do an update or edit to that file away from your desktop/office.

Old program had many functional editing features in the side bar, I cant find any decent editing featrues in this product.

Why it is impossible to have editing options as they were previously? Can a 'Classic view' be added for those of us older than 5?
Everything in this new 'charms' based UI is fussy and time-consuming. I've been using Acrobat since its inception and now I'm having to relearn nearly everything. WHY?
It wasn't broken, so the need to 'fix it' has created a frustrating experience.

I’m trying to edit Javascript in an external editor. This has worked for years until just now. I’ve tried Brackets and TextWrangler with the same failure. Acrobat launches the external editor, and waits until the editor process is no longer running. This means that you actually have to quit the editor after saving the document in order to make Acrobat respond to your input again. This is fine, it has always worked in the past. But now when I quit the external editor, Acrobat remains unresponsive because it's waiting for the external editor to close, even though it’s already closed.

I wish Acrobat to have option "replace all" under Find and Replace.

It would be nice to have the ability to remove just one footer instead of removing all headers/footers. For example, I work on large publications and would like to be able to leave the different headers and copyright footers for each chapter in place, but be able to update the page numbers. Currently, when I remove or update a header/footer, it effects ALL headers/footers. There should be a menu option to pick and choose which headers/footers to alter.

Please bring back the multiple-row toolbars, this is such a step back in functionality!

PLEASE fix so text boxes stop combining. I KNOW Acrobat is not an "editiing" app but I have to make contact sheets from multiple products and sources from Adobe Bridge. Then the client needs a couple changes, or we need to update an area on the contact sheet ONLY. Constantly have to fight to redo text. Not editable in other apps - Illustrator can only open one page at a time. Can't edit PDF in Indesign. Can't edit in Word. These are NATIVE pdf's from Bridge. Thank you.

I would like to be able to generate a table of contents using bookmarks within a PDF. While there are some third party plugins that will do this, it would be helpful to have this feature within Acrobat.

I want to suggest an improvement to Acrobat Professional:

When adding headers or footers to a document, I suggest that the mechanism use the document's page numbers, instead of inventing its own.

For example, my document has page numbers A.1 through A.29 followed by B.1 through B.7 followed by C.1 through C.6 ... followed by V.1 through V.11.

Right now, it seems that the only way I can get the actual page numbers to accurately appear in the footer is Add 22 different footers. That's an onerous task.

I would like the ability to add Roman Numerals in headers. Right now, adding a page number within the Headers and Footers dialog box does not allow me to use Roman Numerals (page labels).

We discovered a word that need to be replaced during our final pdf output from Framemaker so we edited the pdf. Once we copied the Arabic word from our excel spread sheet the entire book became corrupted by scrambling letters, changing font appearances and reversing parenthesis and other characters. Need this fixed.
