Yes.

For me, the titles of hidden windows don't have any text after a resize, 
but is fixed when the focus is changed, or after just a 'refresh' (M-n)

I'm not sure where to start on this bug. The problem could be in my code, 
XMonad.Layout.Tabbed.addTabs...

I can think of a couple ways to solve this, though I'm not sure which sort 
of behavior is better (and adding an option between the 3 choices would 
just confuse everybody):
    0. keep it the same, but just allow groups to be created out of windows 
    adjacent in the stack (ie. don't use windowNavigation to pick the 
    window to merge into)

    1. rearrange the WindowSet to keep the tabbed groups together, so the 
    modifier can keep asking the underlying layout to place the focused 
    window where it would normally be placed
        - tabbing and untabbing causes the WindowSet to be rearranged

    2. ask the underlying layout to place group where the 'master' of the 
    group would go.
        - you won't be able to rearrange tab groups with the regular 
          WindowSet operations (M-K,M-J, windowNavigation...), unless the 
          first tab is focused

>4. A keybinding for only switching tabs is missing.

That shouldn't be too difficult to add a specific message that will do 
that.
