Personally I miss:
BiteSMS - yes Apple has come a long way, but they still have quite a long road in front of them before I would recommend the native app over Bite.
Flux - since I check my phone several times during the night, this is really a must have tweak. And Apple could have easily included it in iOS 8
Bytafont 2 - this is more a wish than an actual need, I just love the ability to change the font.
