I want to share my first work for Rainmeter, inspired by @arkenthera.
I give him some credits for part of the code, the rest has been made with MSDN, tutorials and other people sharing around the world.
Tha skin is simple and already seen around, it makes your taskbars transparent or you can set also with blur behind (like in old Windows 7).
Please, find any other detail on DeviantArt and also the code on GitHub.
The skin is working properly on 2 monitors, I also fixed a know issue when the user lock and unlock the screen.
There is just one issue pending. With some fullscreen applications, the taskbar is forced to retrieve the main Windows theme color. I made a workaround, when it happens you can just click on the taskbar and it will refreshes.
Feel free to ask anything and to work on the project as you wish.
I commented the code as much as I could, but I'm here to explain if there is something unclear. It is written in C# btw.
Here's an example:

Enjoy!
