Hi, guys.

Our project has that requirment: to audit a proposal, will process a workflow, at different workflow node, different roles should see the proposal. I think I should create a Workflow part, and workflowHistoryPart(Used for recored the audit history), but how to Implement/control at the different node just special(different) roles can see the proposalbase on Orchard?

If you have experience on it or have some idea please tell me, thank you so much!

Depends when you need it: workflow is one of the candidate features for 1.7.
