I think you need to spend some time thinking carefully about the problem that you are fixing. Then fix it in a way that is intuitive and easy to use, not just for powerusers but for very casual users.
As it is I don't know what the problem is that you are trying to fix. Are people up in arms because of the color of the notifications? When I look at an app in the app store, I won't download it if the developer can't explain it to me in a sentence or two. I look at your description in the initial post, and I would decide "no" after a brief peek at it, because there is no problem listed that concerns me. Moreover, it just looks so cluttered that if I did try it, I would uninstall it after 15 seconds based on the appearance.
