I coughed up my two bucks for the pro version of GoodWidget (Stack), and it works great, except I think you need to pay per stack (you can change the contents of a stack but I don’t think you can have two running without paying twice). These photos are now from a walk in Sunol Wilderness, just to check the ability to change stack contents. Click on the images to shuffle through them. Source: goodwidgets.com.
