I beg to differ, good sir.
Especially removing the gradients, that would make a massive difference in look.
I'm currently playing with Sense 4A (One V port) some more right now, and I can say that all it takes is a change in colors to make it much more ICS-like.
Yes, the widgets aren't in the app drawer. No, I steadfastly believe that they shouldn't and that it is for the better to have the entire homescreen layout have it's own edit mode where everything can be added at the same time without having to constantly tap and hold and drag shit around.
