PPT Remote Review (update)

I had reviewed a program called PPT Remote when I was looking at Android phone PowerPoint remote control apps. Since the review several of my questions about the app have been answered. I was unable to get slide previews to show, but the developer has come out with new versions of both the Android app and the server for Windows. Now I'm able to see either grey-scale or color previews of the slides on my phone. Great! Plus that shows me this app is in active development. I had given this app 4/5 stars, but the improvements make this a lot more useful and fun to use so with the new version I give 4.5/5 stars.
