Workflow resources (sub-modules, recipes?)

Are there any resource sites for Workflow-driven apps? Someplace that has pre-built workflow sub-modules, recipes, exported views or panels ready for import, etc?

I'd like to have flexibility both with interactive WF state tools (used by privileged roles who push content through the states) and in displaying tables of WF content. But I haven't found any prepackaged stuff, and rolling my own seems like it's very complicated and full of pitfalls (due to my limited knowledge).

Having used many CMSs over the years, I've often seen resource sites for niche modules. Has anyone seen such a site for drupal Workflow?

Thanks!
