Instead of privating all private conlangs, add a filter to make them invisible in the selection of courses to learn.

That means there would be a switch that determines if personal conlangs are visible or not. that would simplify the search for stuff such as global auxlangs and normal langs too.

Happy to hear someone's of the same opinion as me, that's the solution I proposed as well. I don't know React though, so I can't implement it.
