Graphical Workflow Editor

Hello!
I am looking for some sort of plug-in which helps me building rather
complex workflows. Has anyone any experience with this one:
http://search.cpan.org/dist/RTx-WorkflowBuilder/lib/RTx/WorkflowBuilder.pm
There seems to be limited explanation provided on that page.

Does it work with 4.X?

Thanks for your help,

Chris

I am looking for some sort of plug-in which helps me building rather
complex workflows. Has anyone any experience with this one: RTx::WorkflowBuilder - helper for configuring approval workflow in RT - metacpan.org
There seems to be limited explanation provided on that page.

This extension works with 4.0 but is targeted at RT’s built-in
Approvals workflow.
