Are there plugins to add html and rss feed widgets?

I think that those are the most important widgets anybody needs in their dashboards and profiles. Generic HTML to put anything and rss feed to get anything from any place easily. I have been looking for them in the plugin gallery, but could not find any of them. Any way to get them? In the classic Elgg 0.9 we had them: text and rss feed. Have we lost them? They are very important for everybody.
