Thanks guys for the responses. A few things:
1. We're working on the issue that causes Super Admins to not have access to groups. We'll be adding an exception for the Administrator group in the next releases that gives them "always allow" access - this should solve most peoples issues.
2. We're also going to look into a solution that prevents you from having to flush sessions so much - basically adding a 'stale' flag onto the user that tells MODX to refresh their sessions. Generally the need to flush sessions so much is that there's no way to actively edit a users' cached permissions for the session, since they're not directly accessible (for security reasons). However, adding a stale flag should address this and give us a secure level of separation that still preserves the integrity of the session without compromising the speed or loading times of the user.
3. With regards to a wizard - it's really hard to develop a wizard without use cases to make the steps of a wizard. When we've asked for use cases before, silence followed.
If we can get a good list of 5-10 different use cases, we can look into a wizard (either in an Extra or the core).
4. A "simple/advanced" toggle isn't really doable, nor worth it in development. A wizard is a far better solution.
5. Having a Default Resource Group setting is in the feature tracker, I believe, and something we'll look into.
