I have to say I wasn’t too sure about the “My Items” idea but I think it is actually making a difference in my workflows and finding things.
I’m a bit confused about the distinction between “Private” space and the favourite items that sit outside it. I know “Private” space views are not available to other workspace users and that the other items are the starred / favourite items across the entire workspace. But the distinction doesn’t seem to have a purpose. Also, given that outside of “Private” area you are not able to have any folders or structures, I think it just confuses the users.
In my mind “My Items” and “Private” should be the same thing. The only issue are the “stared” items. I think every time you “star” an item it should create a “shortcut” or “symlink” to that view or entity in your the Private space, that you can move around and place where you need it. It would be great if you could also rename the shortcut and give it a different icon/colour.
Having the more generic shortcut item would allow you to also create left navigation bar shortcuts within all the spaces and avoid having to duplicate a view (and have to maintain them each) just so you have that view somewhere else.
