This patch let's you change the order in which types of jobs are performed. For example, previously gnomes would always perform jobs created directly by the player before say from a workshop. Now, per profession, you can set the order of those job types. Individual jobs of the same type are still prioritized as they were before, whether by distance to the job or the priority setting of the workshop, farm, grove, pasture or stockpile. Jobs that are directly created have been split up into 4 groups:
Mining - mine wall, dig stairs, etc
Agriculture - Fell tree, forage, etc
Build - Build workshop, furniture, etc
Mechanic - Reset trap, flip lever, etc
As an example, you could create 2 professions with Woodcutting and Carpentry enabled. One profression has Agriculture first and the other has Workshop as the highest priority. Gnomes in the first profession would act as before and fell trees before cutting planks while the other profession would do the opposite. Splitting up your workforce this way will allow you to work on both tasks simultaneously and let some gnomes act as "backup" and work on another task if their main one is finished.
