there's a really nice module, Context Admin.
the explanation is hard to get, unless you see the videos, but basically it allows you to create pages (usually administrative) through page manager/panels and place on it links (local task) to some administrative tasks, among other things.
you can for example, create a page with path "/admin/manage/banners", and place on it links to create nodes of type "banner", and then add a view to list banners right bellow it.
or when comparing to Total Control Admin,
create a page at "/admin/dashboard/nodes", add links to create any type of node, and then list (or not) the 10 last created nodes as title with links (views)
and same for users, taxonomy, etc, i guess
it would be interesting to see these two modules work together, by having total control use context_admin functionality as a dependency.
total control could perhaps use page manager+panels+context_admin to do all the code for it, and work instead as just a bundle of configurations for page manager/panels.
what you think?
