As a prime example, when you click a node under Content,

It shows

"Create an item under XYZ"

Then I see the items I can create.

What I want to do is create a new section under there

"Change Member Permissions for Test"

Or optionally, I want it to show up as a new Tab when I click on the content on the content editor.

I am using the TreeControllerBase.MenuRendering event to add my menu item to content, and it works. However I have to use the MenuItem.LaunchDialogView to make it work. If I don't it tries to find my view in umbraco/views/content and I don't want to put my view there. And SetActionUrl is private.

What I don't want is to have to click "Do Something Else -> My Menu -> dialog opens"

That flow get's missed by non technical back office users and is tedious. I'd rather it either show up as a tab on Click, or a section under "Create an Item".

Also, I am using e.Menu.NodeId to look up the node for the tree. I only add my menu if the node is based on specific content types.
