Allow/enable Adobe Acrobat Reader DC to add the "Open...[file]" command to the Quick Tools toolbar.

I am using the most recent version of Adobe Acrobat Reader DC as of today 12/1/2020: 2020.013.20064.12623.
When you are constantly opening files, it becomes very tedious to constantly be required to click on the File menu and then select Open... to open files. An Open... command icon is a standard quick command on most other software I have seen. I am surprised and disappointed that no one thought of this or made this a standard command icon on this toolbar. In fact, there are several commands that I cannot even remove from this toolbar that I never use. So, actually, that is another suggestion: don't automatically add ANY command icons to the Quick Tools toolbar that cannot be removed. Every user is different and it would be nice to be able to truly customize this toolbar as needed.
Thank you,
Phil
