Adding hidden list feature to a feed you want to hide

[SELFEMO]

Clear and concise description of the problem

For feeds where we have a feed we want to subscribe to, but we don't want to be able to view its subscription information all the time, we can add that feed to the hidden list. We can only see the information of the hidden feed in the hidden list.

Suggested solution

Add a fixed hide list at the software level for feeds you want to hide
