Well, having renamed 'PresetsAll' file to 'Presets, replacing the original file, it is rather more interesting as a visualiser.
I'd still appreciate hearing about the plans for setting the options and, potentially, importing favourite presets.

MM5 is even more than I'd hoped for- thanks all.
Could anyone indicate whether at some point it might be possible to import my old favourite .milk presets into the new implementation of the program?
