Touchscreen hologram class selector

So recently the amazing folks at HoloAPI (Best hologram plugin and API IMHO) developed touchscreen holograms. This is amazing and I was thinking of all the things this could be used for and didn't know until I saw this: http://imgur.com/a/zgKWp which is an incredible idea. So I am now working towards making a kit selector probably that is gonna be integrated into a plugin where you can select you classes with money (configurable) anyways if you have any other thoughts or want to contribute comment below!

It looks seriously amazing.
Totally innovative. And I wonder how many other possibilities are there, waiting to be discovered...

When they discovered how to make holograms in vanilla, it changed a ton of minecraft servers forever... this adds ways to create custom vanilla floating GUIs... every big server will have devs working around the clock on this, and creating a plugin for this is definitely within reason. Asdjke has forever changed minecraft redstoning.

EDIT: They already created one.
