This worked beautifully mate thanks for the input! 

Is there a way to make newest notification appear at the top of the feed? The oldest are appearing first

But, I know these things are easily seen in hindsight too. 

I can assure you, that now it has been bought to the attention of the team, someone will be working on it soon :) Great ideas 

I feel your pain. 

The potential usefulness (hopefully PM notices will go there eventually too) of the this new functionality is such that one has to strongly consider going with a site + wpforo menu layout. The reason is simple, on mobile devices the entire sidebar is moved to the bottom of the page where few venture to scroll which makes the notification functions somewhat redundant. 

Yes, it's possible. All notification types data are passing through 'wpforo_register_actions' filter hook. For example, you can use this function in your active theme functions.php file:

function my_custom_wpforo_notification_icons( $notifications ){
   if( !empty($notifications) ){
      $notifications = '<li class="wpf-new_reply">';
      $notifications = '<i class="fas fa-heart"></i>';
      $notifications = '<i class="fas fa-arrow-alt-circle-up"></i>';
      $notifications = '<i class="fas fa-arrow-alt-circle-down"></i>';
   }
   return $notifications;
}
add_filter('wpforo_register_actions', 'my_custom_wpforo_notification_icons', 10, 1);

Use, Font-awesome icons <i> HTML code: https://fontawesome.com/icons?d=gallery&m=free

I'm really sorry but it's not possible without tons of custom code. There is not an easy option for that.

I want to add it to the top menu you see:

I have added a pic to give you a better idea of what i mean

If i can add that widget to y menu, it will display on all pages, even pages without a side bar, and give a nice easy option to log in too

I dont want it to display the badges, and points, as they might bee too much in the top bar. But user name, avatar, rank and buttons is ideal if it is possible. 

I know we have that setting in widgets, but I cant add a widget to that part of the page unless it in html 

For logged out users i want it to display, just the login in and register buttons

And for logged in users, I want them to see their name, avatar, and buttons

The "My Profile and Notification" already widget works that way, you don't need to do anything:

I would like to take the html, and add it to my top menu, inplace of my social media icons in the top right. 

For logged out users i want it to display, just the login in and register buttons

And for logged in users, I want them to see their name, avatar, and buttons

How can i do this? This will allow the login and register box to be displayed across my site on all pages. It would be awesome if I could get it figured out'
