Auto sleep building when buff expires
Have a check box for each building to automatically sleep a building when the buff expires.
For example, I have snack on FT Castle that expires in the middle of night. I want to go to bed, but have 4 hours left on buff. If I sleep it now, I lose 4 hours of the buff. If I leave it, I'll lose many beans making only 1 beanstalk at a time.
Wouldn't it be great to select a building, check the auto-sleep box, and know I'll get the 4 hours of buff and then the building will sleep.
Or if it's too hard to put on each individual building, auto sleep classes of buildings. For example, all weaponsmiths, or all gold mines, or all building affected by each of the zone guides (paperwork, wood cutting, mining, etc), or specialty buildings like FT Castle.
