By using S and N in the editor (small/normal) chords can be made more readable in crowded measures.
Remember, each N or S applies to all subsequent chords in the chart. When you use S to make a couple of adjacent chords fit better, please use N on the next chord to reset the rest of the chart.

By inserting space(s) you can make a measure longer but it will affect the appearance of the chart. Some additional adjustments may be needed. (Like shortening a nearby measure(s) that has only one chord to line things up)

Also consider whether it's really necessary to have that extended chord quality on that chord(s)
Instead of X-7b5 you can use Xø.
