I may seem a little picky on this one, but I cannot find a SILVER Star amongst the very fine selection to be had. I am only making this noted as I use the Silver Star as a Secondary achievement to our Suppliers in the Google Play Store. I use the Black, then Silver and Lastly the Gold Star to Show my appreciation of someone's effort and output in the works. This allows me to mark an applications performance by a mixture of Black, Silver and then Gold to represent a truly remarkable effort and thus try to make someone with their work really standout in the crowd of applications. I like to imagine that when I write up my report on an application that it's developers would be very proud of themselves if they were to get 5 Silver Stars or even better 5 Gold Stars. I know for myself ones self esteem would be lifted much higher with a better than 5 ordinary Black Stars that if it's mentioned in one account of the application that a user was prepared to give a Star rating of the Gold or Silver Stars. From my own experience, I know it feels good to be appreciated like this, plus you can use this type of reporting to lift one's spirit when there must be many days where it is a day can be full of drudgery.
Make people feel good because someone is offering Olympic type of awards for their work.

p.s. I really love the SwiftKey Keyboard and I seem to be marking it fairly high in my list of apps in my portfolio. I even tell others of my high opinion of this piece of technology. Well done all of you!
