What I noticed is that as a user I can change the way my screen looks my selecting a different screen type or change what columns I see in a list and the order of appearance. What I can't change is the amount of menu items I see. In my case, I only use a handful of menu items within the Software Factory.
I would like to hide certain menu items because I never open them anyway. Also changing the order of the menu to my liking is something I would like to be able to do.
Edit: This would be a User preference setting, so available for any product (SF, IAM, End product)
