Dongiedong,
It's a good chart.
Two things:
1. You don't need those diagonal slashes. The chord will repeat until the next chord.
2. In bar 13 you can reduce the width of C7 B7 by selecting an "S" from the top of the edit menu over the C7 and then retuning to full width with an "N" over the Bb9.
Cheers,
Jer
