Wish: new simple block-type: like chunk but without chunk

Would be nice to have a block type without any specific function, just with two fields: template and custom preview. It would be identical to the chunk-block, but without the need to choose a chunk. All the settings should be available, too.

This could be used for quickly generating small pre-defined chunks of HTML-Code (with custom settings) but without the need to create a separate chunk and pass all the settings to it.

At the time being, if you don’t choose a chunk you get an error message in the manager, so for now I create an empty chunk “void” and choose that in such cases. But this is not very elegant.

How would you call it? “mini-chunk”, “empty”, “joker”, “custom”?
