Completely kill Acrobat DC - what a piece of junk.
Acrobat DC makes you hunt through a menu and multiple clicks just to pull up each tool. And this is for each single PDF that is opened into the interface. Honestly this is just so bad. I want Acrobat to look exactly the same each time, with all my commenting and other tools lined up in menus on the right side. Every time, when I open any document, so that I can work.
Thanks for Using Adobe Acrobat. If you want your specific tools to appear always on your Toolbar , you can always add them to the Top Toolbar using the "Customize Quick Tools menu" .
Please have a look at this article https://helpx.adobe.com/acrobat/using/workspace-basics.html and refer to "Toolbars" section and view "Quick Tools" options.
Let me know if that resolves your concern .?
