show badges immediatly without page reload

It's an interesting idea, but I probably don't have time to write this. You would need to add a javascript polling loop that periodically checks for updates and adjusts the badges as needed.

If you (or someone else) want to provide a patch, I will integrate it into this module.

Sounds like a good use case for node.js leveraging socket.io (or something similar) for push notifications.

I'm sure this feature would be better with node.js, but it's significantly harder for most users to set that up. A polling loop would work on any server.

Either way, I still don't have much time right now to implement this and welcome patches from others.

Maybe using AJAX with Views? Don't know...

Polling loop would work, but it does add extra unnecessary traffic to the server.

you can use https://drupal.org/project/views_autorefresh

check also https://drupal.org/project/block_refresh
but you need to add link_badges.css to your html.. put this lines into your theme preprocess_html ..

drupal_add_css(drupal_get_path('module', 'link_badges') . '/link_badges.css');

If you can render the menu using a View, and have badges based on flags, you could potentially use the Views Flag Refresh module for this.

Can somebody confirm that Views Flag Refresh works? It doesn't seem to be working for me.

Cool module.

I am also trying to update the counter. I tried Views Flag refresh to work, but I see there is no "AJAX" option on the Menu Badge display. I also tried refreshing the view via js, but the counter on my menu link is actually wrapped in a span and not a view, so I 'm stuck. Any pointers?

Block refresh works.
