Finally got the preset tool finished. Currently for Windows only, though I’ll try to get an OSX version out shortly.

This tool allows you to change the algorithm number of a preset. If you load custom algorithms into a different location than the developer, the presets for that algorithm won’t load unless you modify the presets. This tool does that for you. Make sure you read the manual. You’ll need gzip to be installed, and added to your PATH in windows.
