Please consider adding a <HR> type markup

I add multiple "blocks" of sometimes formatted content to the same page and it can be hard to differentiate between them quickly.

A <HR> type markup would be wonderful to help split content into logical blocks for me.

From Wikipedia:
<hr>
    A horizontal rule. Presentational rules can also be drawn with stylesheets.
    Standardized in HTML 2.0; still current.

I apologise if it is available and I missed it.
