I looked at the Personal Workspaces folder. We don't use any special folder definition. (Although I did reset the definitions last night to get up to the 2.1 set up.) So, unless the reset undid something I don't know why you aren't seeing the list.

In the next release, I have added a new role/right called "Can see binder title". This role will let you designate that a person can view a folder but unless they have the "Read entries" right, they won't see any of the entries in the folder. This lets you give some people the ability to view everything, while hiding the entries from other users. This would work perfectly for what you want to do.

You could also solve your problem by making a custom version of the profiles list jsp. All you need to do is turn off the folder list for everyone except those is the admin group.
