Feature Request for Blocks / Record Feeds: Ability to toggle what content displays from the record

I love the new block feeds. However, they show too much information when the records displayed get smaller.

My feature request is a way to toggle on/off which fields from the record should be displayed on the block.

We use a teaser field for all of our articles, so the block automatically includes it:

But on this style of block, it looks messy. I also don't want the comment count there, or at least be able to toggle it on/off. For these blocks, it should be relatively minimal text. Title, By-line, Date. Done.

The reason extends here also where get both the Author and who updated it. I don't need the updater at all, I frequently edit my writers' work, but I don't want that showing on the block. I also don't want an excerpt of the article text. For these blocks, it should be Title, By-line, Date, and Teaser.

Displaying tags and number of views should also be optional.
