One of the "issues" with ES1 is the inability to use tracking to look at task assignments that occur in a subprocess of the main process instance. I read this in the documents.
On the Status tab, you can view the names of the multiple users who are part of the task, the date they completed the task by, and their comments on the task. If the task was forwarded to another user, you can view their comments as well.
If a process that has multiple users receiving tasks in parallel and the tools for reviewing documents are enabled, to view details of the users who are part of the task, click the Status tab
This seems to tell me that if you use the task assignment component to assign to multiple parallel users, you can see the multiple parallel users in the status tab.

I don't see this is fixed either in ES2 or ES2 SP1. I am also designing a very critical multi sub-process workflow.
Due lack of default tracking, I'm unnecessarily investing lot of time to create a custom Audit & Tracking.
Yeah, I wasn't sure if Jasmin's comments related to ES1 or ES2.
I've built a custom dashboard on flex and data services using database views that join livecycle tables with custom tables. It's nearly as functional(or moreso) as the entire workspace. I can sort tasks on any arbitrary data. It's getting to the point that our power users are only using workspace to approve/reject/submit because of the workspace limitations when working with complex/large number of processes.
