I think there needs to be a Pro version and Reader version just like on desktops.There is no reason why the i Pad Pro can’t handle a pro version.One of the main goals was to have all of a user's PDFs available on any of the user's devices, such as editing a PDF on an i Pad and then later retrieving it on a PC.The UI had major changes with the introduction of Acrobat DC in 2015, which supports Windows 7 and later, and OS X 10.9 and later.
FILL AND SIGN FORMS• Quickly fill out PDF forms by typing text into fields.• Use your finger or Apple Pencil to e-sign any PDF document.
Adobe also allows third parties to develop Acrobat plug-ins, which can add extra functions to the Acrobat program.
Adobe has changed the names of the products of the Acrobat set several times, also dividing, merging, or discontinuing products.
So if a restart must be performed, it would help to be notified of this.
I use this a lot to mark up PDFs but there a few UI improvements needed.
