This global vehicle specialization is added to most fillable vehicle such as trailers, trains and seeders.
The user is then free to set the maximum fill limit they wish the trailer to stop filling at. Very usefull if you only want to collect a set amount from a silo or buy point.
Limits are saved for each vehicle and can be reset whenever required in the GUI.
Important: This mod by design will not allow the max capacity to be increased above the default level.
Specialization is no longer added to tree planters, straw blowers or belts due to undesired results.
Fixed bug where using shovel on a heap with limit set would remove more than required from heap.
