Factorio no longer loads this mod because it no longer accepts a setting for the custom hotkeys.
The fix is easy.
in data.lua change each 'consuming' value from 'script-only' to 'game-only'
data:extend({
{
type = "custom-input",
name = "inserter-drop-distance-toggle",
key_sequence = "CONTROL + F",
consuming = "game-only"
}
...
