After searching for a while, I think there is nothing out there for 3.2.x, which would fit my needs. I'd like to see an extension, which adds a "permission to edit" section into any custom profile field.
Say you have a counter, like "Sessions Played", which is entered as value for a custom profile field. The field must not be edited by the user itself, as it is tracked by some Dungeon Master or whatever, but needs to be seen by everyone. In best case it is possible to set the permissions for single users even.
To visualize the picture above shows that the value is changeable by the user itself, which must not be. But it should be visible still for everybody.
If someone has an idea how I could achive that without any extension request, I am happy to try!
