Once again thanks to KiwiDude for his modified plugin code and to Yankoa on Deviant Art for allowing the use of his wonderful Metro Icons. And off course Kovid for creating this awesome program.
Main GUI skin is complete. The following Plugin images are also included:
Search The Internet
1. Back Up you existing AppData/Roaming/calibre/Resources folder.
2. Extract the zip file to your AppData/Roaming/calibre/Resources folder.
3. Restart Calibre
Note: I did not skin any plug-in icons that are tiny (32x32) as it did not look good.
