A lot of requests are already posted to remove the blue share button...
Well the user should be able to customise the Acrobat Pro top toolbar.

About the Share button: Please give the user the choice to CUSTOMISE the contents of this Share menu. Let the user hide apps that are not used and add apps the user does use.

For example:
In my case I do not use Outlook, Teams or Gmail... But I do use Nextcloud (cloud service) and Thunderbird (email app) a lot.

Please give users a possibility to customise ALL menus. This was possible in the old interface, it should also be possible in the new one.
