@zogstrip I started to work on this; I’m going to create a mentioned notification type (in frontend/discourse/app/lib/notification-types/).
I’m using the other notification types as example, and I noticed the usage of this.siteSettings.prioritize_full_name_in_ux (note, it’s not prioritize_username_in_ux).
Its value seems to always be false (like, on a “like notification”, the username is used instead of the full name).
A small grep for prioritize_full_name_in_ux = shows me that it’s only assigned a value in the tests, so it keeps its default value defined in config/site_settings.yml:1005 (false).
Am I missing something or there is a bigger issue here ?
