Invoker's App Launcher

A simple excercise in LUA and Rainmeter. Dota2 inspired, Invoker style application launcher based on a great wallpaper by Voxelflux.
Wallpaper available here.

How it works? This little .gif I made shows it quite well. Set your own paths for up to 10 applications/folders/whatever, and each gets assigned under a specific combination of Quas, Wex and Exort. Click on the runes to activate them, you can see your active runes as small dots. When third rune is activated, corresponding app is launched. If you mess up (want 3 Exort but accidentally clicked on Wex, for example) you can click the little cross to reset. Cross is not visible if you don't have active runes.
Order in which runes are activated doesn't matter, only how many of each. The little question mark shows a cheat sheet. Click on the sheet to close it, click on the question mark to show it again.
Quite simple, really. Inefficient, too. But it's a cool thing to have on your desktop.

IMPORTANT! Currently the resolutions are 1600x900 and 1920x1080.
In other screen resolutions, it should work well with most wallpapers, except the one meant for it, since the meter runes won't line up with wallpaper's ones. You'll have to modify the skin and change buttons' sizes and positions for it to display properly in different resolutions.
If you find out the size and position values to line up the runes with wallpaper on different resolutions, let me now so I can update the skin!
