I prefer to sharpen my photos with unsharp mask, because of finer results compared to built-in sharpen effect. So far I had to use other programs for that operation. Switching between programs is annoying - so I decided to learn the code and design a plugin with features I need. Hope you find it useful too.   Menu location: Effects > Photo. Download as part of my plugin pack.     Updated to version 3.1 (2008-12-24)! Changes: few UI and code optimization
