Can the Plugin create a post on the User’s feed whenever they upload a file?
Yes. It’s possible to post activity on their feed whenever they’ve posted a file, this is toggled in the Activity Feed section of the Plugin Configuration settings in the PeepSo settings on the admin panel (Peepso → Configuration → CM Download Manager).
To learn more about activity feed posting see this Help Article.
Can I customize the activity feed post that is posted when a user uploads something?
Can the link to the users’ Manage Downloads sections be added to the widget?
Can I enable and disable the display of a tab in the users PeepSo Profile to go to Downloads?
Is it possible to change the icons that appear for Downloads or Manage Downloads within the widget?
Yes. The icons that appear here are from the DashIcons library. There is a field within the Plugin settings that allows for the icon to be changed by selecting the CSS class of a different icon from the library.
Go to https://developer.wordpress.org/resource/dashicons and search for an icon that you would rather use. Copy the class given and place this into the field in the PeepSo Downloads Manager configuration settings (Peepso → Configuration → CM Download Manager → Profile Widget).
