[Looking for] Sidebar sub-menus

Hey there,
I am looking for a plugin which will display the pages which are in the same sub-menu, as the one you are in, into the sidebar widget.
For example
Main menu
-sub 1
–sub 1 content1
–sub 1 content2
-sub 2
–sub 2 content1
–sub 2 content2
–sub 2 content3

So if you are on the main menu it will show “sub 1” and “sub 2”, and if you are in “sub 1” it will show “sub 1 content1” and “sub 1 content2”, etc.

Also, it’d be preferable if these are configurable so that I can edit what the bullet points look like (as I am looking to have these in a bulleted list)
