Contributors:
Special thanks to Michael Zülsdorff for feedback and testing, ensuring this release meets user needs effectively.

Mischael, great feedback
think i got it working

Next I'd suggest to surround that line like

if (ossn_isAdminLoggedin()) {
    $user = $username ? ossn_user_by_username($username) : ossn_loggedin_user();
} else {
	$user = ossn_loggedin_user();
}

because otherwise any user may collect any user's data ;)

And since all this belongs to the member's personal data anyway, I would make it part of the "Edit Profile" page like

(The GDPR component shows which way to create an entry like that)

Some changes ... just having a first brief look ...

define('__CLIPBOARD__', ossn_route()->com . 'Clipboard/');

remember that Unix file and directory names are case-sensitive
and your component gets installed as Clipboard - not clipboard

ossn_extend_view('css/ossn.default', 'clipboard/css/clipboard');

Ossn expects css files included like this to be PHP executables (allowing to use some vars) - so rename it to clipboard.php

/*
echo ossn_set_page_layout('contents', array(
    'content' => $content,
    'title' => $title,
));
*/

Have a look into themes/goblue/plugins/default/theme/page/layout/contents.php:
It's dealing with content only, thus it makes no sense to pass a title parameter. And if you don't want a standalone page but include it (as shown in the screenshot) the complete change is:

$page = ossn_set_page_layout('contents', array(
    'content' => $content,
));
echo ossn_view_page($title, $page);

Great!!! Like said feedback about working css would be great. But this looks great

Really useful. Thanks Eric!

Ready for testing. This was a lot of fun and took weeks, but I finally have something to show.
Inspired by exploring the Wall, Blog, and Feedback code, I created this module.

The result is an overview of all your posts and reactions.

In this version, the post limit is set to 1000:

// Fetch timeline posts
$wall = new OssnWall();
$user_posts = $wall->GetUserPosts($user, array('page_limit' => 1000));

In the next version, this will be set to false for unlimited posts.

Enjoy using it, and please provide feedback!
I’m still struggling with the CSS, so any help is welcome.
