PLEASE UPDATE! Bugs! Otherwise great

This is my go-to app-the many list options, how they are all laid out & everything - but of late, items keep disappearing! Otherwise, please add a save button I can hit after each entry.. because sometimes as soon as I add an item, I am taken out of the list/or I exit myself and to my dismay - my entries (I JUST ADDED) are gone
