Great game but please add confirm or undo features! – My Little Farmies Mobile Review

I have cerebral palsy, can't speak must play games to improve my dexterity and hand-eye coordination so I can "talk" via text. This is one of few apps I can access with any success whatsoever. Will you please consider adding optional confirm and undo features so I don't mess up my farm? I can't figure out how to expand the pens in order to include a manger. I keep messing up! I love this game! Please, please help me! Thanks!
