Looking for Widget enhancement plugin

I am looking for a plugin that will allow me to customize my widget visibility. For example, I’d like Widget 1 to appear only on my homepage, but I’d like Widget 2 to appear on every page and Widget 3 to appear only on individual posts, etc.

My current theme is K2 and it has this ability, but I’ve been wanting to explore other theme options. Is there a plugin that will give me this functionality?

Thanks.
