Navigation Pane Sucks!

As a new user of Wrike for a week I just want to express how much I hate your navigation pane. Too cluttered with junk tabs I don't want (personal, bookmarks, bin, explores spaces, shared). Can't reorder any spaces or projects into a logical way without changing project names or adding numbers that create unnecessary confusion. I'm really surprised by how user unfriendly it is in 2019
