Enharmonics: Replace chosen accidentals with their enharmonic

EDIT4: tpc values are int not string (innocent mistake)
EDIT3 For discussion see: https://musescore.org/en/node/360437
EDIT2: Added start/end Cmd required for MU4 apparently...
EDIT: Fixed an error in Component.onCompleted
Background: A user (https://musescore.org/en/node/359686) requested the ability to eliminate double sharps & flats from a score by plugin. This plugin does just that in default config.

To customize the plugin to your needs:
Open the plugin in a plain text editor
Search for: var enharm
Comment/uncomment the lines thereafter as desired
(a commented line starts with // and does not execute)
