This is what you want.
There is a way to get rid of multiple traces over the same lines.
If you go into menu 'u' and look at the on-off options at the bottom, option 'd' equal segment removal in minimizing is off by default, because it can make the whole process take a lot longer. But if you know you have multiple traces over the same lines, then with this set to on they will be removed when you minimize.
I also exploded this frame and glued the multi-part letters together with "lit black vectors" !!!
Then I collapsed it again.
