@ecujak, check out this (2008) video on Navigation. The designer looks a little different, but the navigation principals are still the same.
As far as the tab strip, that works a little differently. When set on the default “Swap to window” Navigation mode, you need to do the following: In the Tab Data dataset, the NAME field needs to match your window names exactly (it is case sensitive). You can show whatever you want in the corresponding DISPLAY_NAME. The best way to edit this is via the Tab Strip Customizer, by right clicking the tab strip -> customizers -> tab strip customizer (or Cntl+U).
