It was not revealed for sure in the trailer or other promotional videos, but brought up elsewhere. It would be nice if we were able to size and re-size the area on the mouse tool for specific placement or harvesting with the correct tools. Example: The Gold Hoe from Harvest Moon would prep the earth in a straight line 6 tiles long. Stardew: Similar Tool can prep anywhere from 1-6 tiles by choice using a drag-box to determine length. Just a thought. Thanks. *Edited for SP
