Well, i just installed this new plugin and i’m trying it right now.
It’s a simple formatting coloring plugin. The file is courtesy from Jamezila from his tutorial on post processing bloom/blur effects.

And here is the shader he used. (Just for trying language marquers on a shader, and it looks like csharp marquer is the most appropriate)
// bloomatic.fx
sampler samplerState;
//Width to sample from
float mag;
//Alpha value
float alpha;
//Operate on a high range (0.5 - 1.0) or the full range (0.0 - 1.0)
