Custom Navigation bar = pain!

[steve.ledger]

OK when I do that "Ctrl+Click to select the yellow rectangle.." I can certainly delete the square, but there is no option to "replace" the square. I don't get the option to "replace" the current yellow square with the one I just copied or can import and replace? I still don't see how to do this. I just need that more golden square there to replace your bright yellow square.

Just replace the yellow colour using the colour picker to copy the 'golden' tile colour.

And and even bigger problem is, I can't get the whole thing to act as one nav bar.

Delete all but the far left button and then from the Navbar dialogue, 'Double-click to add new button'

Changes made to attached file (you can handle the button background colour again )
