Barn doors

I love to build barns but the current doors just don't work well. When moving cows, sheep & horses into/out of a barn they frequently get stuck on double doors, and forget about gates! If more than one animal wants out they get all jammed up. Wide barn doors that slide apart would allow sheep especially to get thru! I frequently move sheep to different grazing spots and sliding wide doors of some kind would look better and FUNCTION better. Thank you Mojang!
