I for one find s2 extremely useful because of it's flexibility and power, and with that comes some complexity. There are other solutions out there that are simpler, perhaps with a prettier UX, and if they work for you, GREAT. Use them.
S2 is great in part because of it sophistication!
Updated features are always welcome tho.
I think after two years its not unreasonable to expect an update and I for one are expecting one, or news of one, SOON.
