What plugin to work on?

I have had an itching to work on a plugin.

I wanted to ask the community what they were interested in.

A few months ago people wanted

1) A docman plugin

2) a karma mambot that worked with CB Karma plugin

3) paginated article (which I hacked through so it is done but probably needs improvement)

Just curious what people are in to.

Fix all the bugs in my open source plugins

Seriously, a quick and much needed thing would be a content mambot that would show one CB tab. Similar to tab wrapper module, but as a content mambot.

A second thing would be a system mambot which adds all CB fields to the joomla $my object.

Third would be an all in one input validation plugin.
