I have been using windows mobile phone since 2010, pretty much since they launched what was called windows 7 at the time. I was excited about it because it had a completely different look than any other O.S out there (namely Android and iOS).
But it was lacking so many features, to name a few: you couldn’t resize the tiles, no background image capability, the notification bar was limited and wasn’t there early on, among many other things. ( we’re not discussing the app market, as I am hoping it will eventually grow).
The good thing however, is that they kept on pushing new builds , and of course with a new build you get new features, so my phone was bumped to windows 7.8 and then 8.1 and of course by joining the insider program , you get to volunteer your device as a guinea pig, at your own risk. That too, was ok with me, as long as I was getting new features.
Recently I bought my HP Elite x3 running on windows 10. It is a great device, but other than windows hello and perhaps the biometric recognition, there wasn’t much change to visually identify it from the previous versions. As a Microsoft windows phone user, I feel like it’s no different than an iOS or an Android, the software remains the same, and there would be minor tweaks to the Hardware.
Now I have seen several concepts out there, and I thought to myself, wouldn’t it be nice if on top of the existing concepts out there to just add one more, namely the 3D concept. it would look something like this: 
It is self explanatory. Whenever you have a message for instance, you will still see the number of messages waiting to be read, but you will also have this elevated box (3D rendering above), which will visually stimulate you to check the message, or at least point you in that direction. Once opened, it will return to its flat format (2D). it would feel like popping a bubble wrap.
Now this may not apply to all tiles as some of them are static, yet still this minor UI change does go a long way in making Windows Phone an even more unique experience to its users.
Feel free to comment and give your thoughts on this concept.
