This has probably, almost certainly, been asked of before.
It would be helpful if hired workers could be instructed to convert nearby already felled trunks into logs. The conversion to logs seems to take 3 times as long as felling a tree. This would be an addition so the helper could be set to fell trunks then asked to log convert nearby already felled trunks.
It might also help if they could continue nearby paused building works. There are too many options to just have them start on their own. The player could start and abort, or fatigue out, to have a helper finish the task.
