Hi there,
Your question it's pretty common. In my experience you usually end up writing your own interface for your own domain using a technology that your company feels confortable with. For demo usage, or for showing the capabilities of the BPM System you can use the current console. The community tryies to improve the current console, but it's a lot of work.
We surely can create a wiki page to have a rank with a set of the most important features that users consider at the moment of choosing a tools for end users.
What do you think about that? Then based on that rank we can create Jira (Project) Issues or feature request so the community knows what's important.
Cheers
