Node 'drafting' functionality with node-type management and Views integration?

Hi all,

I seem to have three options here:

http://drupal.org/project/draft
This one is closest to what I'm after. There are a couple of issues with this one - I need to have this functionality working for one content type only on my site. Additionally, there is Views integration here, but it doesn't unlock the filter I'm after - namely, a content type filter.

http://drupal.org/project/save_draft
The same issue here with content type management, it's not enough for what I'm looking for.

http://drupal.org/project/save_as_draft
Very similar to the one above. Again, no Views integration.

The objective is to have a 'Save as Draft' button on node creation forms that will save the node to be finished later. I would like to have this enabled for specific content types only, and Views integration to ideally create a block of drafted content by the specific user and the chosen content types. I have had the idea to remove the button (via CSS) in all other node type creation forms, but that's a messy way of doing it and will cause problems if I create new content types elsewhere down the line (which is a reasonable possibility).

Anyone have any ideas?
