Navigation Bar

Hi,

In MS 3, to make the navigation bar more useful, I would Crtl- T to put text above each stave. The text would be enlarged to say 20 pt and coloured red. If you made the navigation bar small,. say 10 mm high, this red text would asppear as a red wobbly square. This was useful to me because I could put such text at the start or each verse and say a blue one for a chorus. I could then very quickly jump to where I wanted to go by moving the navigation 'cursor (the pages of the main score in vie.). So if I made a change in verse three, and I wanted that change to be the same in the other versus, I could copy it and quickly get to that verse and paste it, rather than horizontally scrolling back and forwards, searching, trying to find that verse
Now:

1. In MS 4 there is same navigation bar, but it is a bit faint. So you can't see these red squares.
2. Is there a better way of doing this?

Thanks,
Henry
