PriorityDesignations

This mod makes vehicles prioritize Leveling designations (hotkey N) over mining and dumping ones.
It allows to create smarter operations and define "Critical sections" that should be done first, before the rest of the job.

It allows creating "Critical sections" of mining or dumping operations. For instance:

1. You want to use as many excavators on that ramp as possible to finish it sooner. But you don't want to assign more than the ramp can utilize and let them idle.
2. You want to connect two islands with a dam. If too narrow, trucks will block each other and progress is limited. If too wide, it takes more time and material to built.
3. There's a narrow passage in between mountains and you want to widen it. The first slide closes the passage and it usually stays closed till the entire job is done.

In all these situations it would be great to mark a "Critical section" of your operation and all vehicles address it before the rest of the work if available.
