Getting the admin-interface correct is one of those holy grails. The problem I typically run into is adding complex wizards or features outside of the standard crud stack.

When I'm investigating an out of the box admin interface I'm _less concerned_ about how they handle CRUD; that's the easy part. Really I need to know how they handle things that go well beyond their stack.

For example, in one application we need to create events for people (like google calendar). You need to be able to search for people, show the system what they already have assigned at that time and allow you to choose times that are best for everyone in the list. This has been designed as a multi-step wizard and it works great but it was a ton of custom code. Looking at the online documentation of flask I'm not sure how I would go about integrating something like this.
