You should put this in the proper place for bugs and requests on GitHub, the author rarely visits here and would have no way to track issues unless properly documented.
Edit to add:
Looks like you could set it in the ini file manually (in text editor) see the example of part of the file
retract_speed = 30
rotate = 0
scale = 1
skirt_distance = 2 <----------
skirt_height = 1 <----------
skirts = 2 <----------
slowdown_below_layer_time = 15
small_perimeter_speed = 60
