Well I've finished it - originally get rich quick scheme number 427
but more like another trinket/bauble that hopefully enriches your Audition experience.
You can download it from here

Essentially AuditionFX (all the good names were already taken) allows you to backup, rename, replicate and delete your custom Audition Effects as well as safely backing up Audition's INI and XML files. It also transmits the name of the selected effect to Audition's open 'Add Preset' window. Handy when the name of the effect or the full name of the effect is not displayed in Audition's drop down list.
As always all care and no responsibility and back up your AA settings before fiddling with any ini or xml files.
AuditionFX is not necessarily for everyone but as usual it is donationware.
By all means let me know if you find any bugs (I think I hid them all pretty well) or suggestions for improvements.
