I plan to revisit this script fairly soon to make it less dependent on maintaining parallel hierarchies (perhaps by storing the UUID for a DevonThink folder in the note field of a project).

The idea is to be able to make changes in OmniFocus (folder hierarchies, position of particular projects within these hierarchies) without losing the link between an OF project and a DT folder.

Its possible that the new script may also be more helpful for your particular work-flow.

(Very happy to share scripts that I write to meet my own needs, and it might well be diverting to offer a customization service, but the days, alas, are short, and of uncertain number :-)
