ShowCase is one of my favorite tweaks because your virtual keyboard will show you lower case when you are typing in lower case and uppercase when you are typing in upper case. That makes what the shift key looks and how it operates like a moot point. If Apple just implemented this simple feature, no one would care about the shift key color differentiation. It makes sense and it seems like a simple fix for a virtual keyboard. It's probably my second favorite tweak.
