The second one I found, thanks to Jeff Schertz blog, is a gadget by Dmitry Polzin. This is a handy gadget for those that typically have a lot of simultaneous conversation windows open at the same time along with other clutter that is in the taskbar. This makes finding the conversation window you want a little easier. This is also a common complaint I get from users. Both seem to work fine with MOC 2007 R2 (RTM) also.
One thing I also like about this gadget is it can be dragged on to the desktop. At the moment I am trying both out to see which one is the more useful and will stay long term.
