They have all you need
Space between sprites, rotation, pvr, trimming, cropping, border, dither, resampling algorithms all you will need from a texture editor
Physics, you can auto trace shapes in concave and convex ways, you can optimize the shape, you can create multiple shapes per sprite, you can assign user properties per shape in order to have more information hen collision occurs, you can make some shapes on the sprite sensors and some non sensors for greater flexibility.
Animations, different time per frame, user info per frame, live preview, notifications like anim has ended, anim has chaged frame, anim has ended all its repetition and many more
As for shapes on an animation, the body will be the body of the first frame. If you change the body during an animtion on each frame, that is slow and impacts fps, you can do its not desirable.
In levelhelper you can define shapes for grouds using bezier tool (which can also act as lines for more squareness) and you can apply a tileing texture on it, make it invisible or whatever your hart desires
