Notification Offline-User / Username Link Template

Hello dear users
First of all I would like to thank you for this fantastic plugin. In my opinion, this plugin is the best self-hosted chat system that I found after various installations.
It fulfills all the specified features, is fully configurable due to the shortcodes provided and has a good performance. I have found no incompatibilities with the plugins I used and it could be seamlessly inserted into my template. For this reason I give 5 out of 5 stars with good conscience, it is absolutely worth the money

However, I noticed two points

1) the shortcode [anonymous_login_enabled] and [link_wp_user_name] in combination with [link_user_name_template] generates a link to a non-existent profile despite anonymous users, which then generates a 404 error page

2) Private messages for offline users only work if the option [users_list_offline_enable = “1”] is set. But since I have more than 4000 users, it not only looks ugly, it also slows down the page load.
Would it be possible to introduce a new shortcode, eg [users_list_add_to_offline=”12345″], which also adds the offline user “12345” to the online user list = [users_list_offline_enable = “0”].

So I could elegantly integrate the chat system into every user page, which can also be contacted offline and without integrating the huge offline user list

In any case, the chat system is the best I’ve seen so far, but in my special case I can only use it for online users

Happy new year to all of you

Greetings marc
