I noticed in Moodle 3.6 (it might have appeared a little earlier) that users can hide from being shown in the Online Users block (see attachment.) Yes, I can understand, especially for course managers, teachers, and administrators who do not want to be shown as being on. However, I am puzzled that it appears that there is no way to disable this feature. In my own case, I really don't want students to be able to hide, especially from me. Yes, I tried it and found that if a student decides to "hide" that even I, as the manager of my moodle, will not see who is online. And it appears that this setting persists (meaning that a student seems to only need to set it to hide once, and then they are always hidden.) Worse, this setting controls who I see as online in my own Dashboard! Before doing an upgrade of my Moodle, I always check my Dashboard to see who is online so that I know if it is a good time to upgrade. But now, students can hide from me!
So, I am asking how I can control this feature. Is this controlled somewhere in permissions or roles? I looked for a setting somewhere in Site Administration and did not find it. It seems to be a feature that should be controlled at both the site and/or course level.
If I cannot control it, I will probably create a feature request for it, but I am not going to do so until I learn if there is already some control provided and that I just don't know where.
