In case anyone hadn't heard and had missed not having it lately, I just came across ithis today. It's from the Xperia2 I think? Anyway, as you can see in my screenshot, it works great on TPs! I'm not sure why RZ ended up taking the other one out. Too many issues no doubt. This one pulls up the same way from the right corner except there's no double tapping or having to play around to get it to pop up.
Edit - I just found these over in NRGZ thread. The first cab in the list, the one I had already posted and the one in the screenshots, looks blue to me. Maybe it's the same one as the second, I'm not sure. I think the original is orange I read somewhere.
