Code coverage plugin for eclipse

I needed a code coverage tool to check how good of a coverage my unit tests were doing. Looking around a little for a code coverage tool for eclipse, I came across ecobertura. I only played around a little with this, but from first looks, it seems quite handy. It gives you a nice highlighting of green for lines of code that got executed, and others in red. There are some other features that I did not get a chance to check out yet. One problem is that there is no way to toggle off the code coverage tool, probably something the author has in mind to add I am sure.

If you decide to use it, please let me know how it goes for you in the meantime.
