[Neos] Questions on plugin development

[Lorenz Ulrich]

Hi there

I'm currently developing a small Neos plugin for fetching an album from 
Flickr via JSON and creating a gallery (new approach for my gallery 
"problem"... :-)).

Now I have some questions

In my NodeTypes.yaml I define TYPO3.Neos:Plugin as superTypes. What is 
the difference betwenn those syntaxes:
   superTypes: ['TYPO3.Neos:Plugin']
and
   superTypes:
     - 'TYPO3.Neos.NodeTypes:Headline'
?

Can I somehow use both superTypes Headline and Plugin to create a Plugin 
that has a content-editable headline?

The only plugin property I defined was the Album ID (album). By default 
I get the "Plugin Settings" Package, Subpackage, Controller Name and 
Action in the Inspector. How can I get rid of these?

How can I access a node property in my controller? I guess there is some 
magic, but I didn't find any hint in the documentation.

My plugin renders a list of images (<a><img></a>) and has inlineEditable 
set to FALSE. Still Neos somehow feels responsible for the content. 
After loading the images as expected the rendering changes to what you 
can see on http://snag.gy/EgBpL.jpg.
Did I miss something?

Thanks and best regards,

Lorenz
