There's no way to increase/decrease the number of lanes to set

Will be fixed this weekend

More of that, when taking a belt or a pipe into cursor:

P.S.: still looking for a way to turn off belt highlighting in new games by default

Should be fixed in the next release of Picker Atheneum.

Disabling belt highlighting is on my todo list.

The error is back, when I change the square size of landfill or stone blocks:
5610.539 Script @stdlib/stdlib/core.lua:46: PickerBeltTools:PickerBeltTools/scripts/belt-brush.lua:40: attempt to index field 'place_result' (a nil value)

Please fix.

I can't reproduce this
