Well thank you for those ideas

D00rstand is old and from when I was just starting to learn obj-c

I probably shouldn't have released it even, it was that bad

Coding inside is horrible, and it is not very nice or dynamic :/ (as well as broken functionality wise...). It could be redone, although I don't know if it is really worth it seeing as not many people even use newstand on iOS (well, I'm sure some do, just like some people use the stocks app

).
Not sure about the weather, it would have to be hooked via a tweak to put in any animations (which as you said, is heavy). It may have background images for different weather though, built in that can just be themed though, I'm not sure
