In the course overview block, courses can be hidden which is a great feature.
Afterwards, hidden courses can be found again by choosing "Hidden" in the course filtering dropdown.
Now, only hidden courses are shown. However, this fact is only visible by looking at the filter setting, not at the course itself.
I would propose to add a "hidden" icon in front of the title of all hidden courses just like there is a "starred" icon in front of all starred courses. This should be done on all display modes of the block (Card, List and Summary)
It has to be noted that this issue has to be done after
MDL-64094 as there has to be a decision about the "hidden course" icon first.
