Increase the maximum width of the paths in the Path Size slider
The existing range of path widths is great for tracing line art, but many logos use very wide letters and stripes of color. It would help if the maximum width were about three times as wide as it is now.
For example, this logo was traced using the widest path setting: https://www.facebook.com/robert.frazier.5437/videos/2350631114977991/. It would look better if it were traced with just two paths, one on the left and one on the right, instead of having to trace an outline and fill it in.
