Does paperless have the same support for workflows and indexes as Mayan? I use these two features heavily to automatically place documents into a hierarchy (eg payslips into their financial year). That and the ability to add arbitrary fields like 'parent', which then means I can created a linked list style association between documents, for example a series of correspondence. It's been a while since I looked at paperless and its forks, but I understand it's not quite built to have such extensibility/flexibility?
