Cancel extra tab for certain block tags (enhancement)

[CyberMango]

Is there a way to cancel the automatic addition of an extra tab indentation when a block tag is closed? i mean, for a modifiable list of tags, instead of expanding the tag to this:

<p>
*tab*
</p>

expand it to this:

<p>
*no tab*
</p>

and preferebly, with an option to do this for all block tags.
