Identifying multiple instances of Eclipse

I have learned to identify multiple instances of Eclipse by looking at the perspective window or "about eclipse" in help.  But I found that inconvenience because it requires me to interact with the menu.   I want to be able to identify the Eclipse Instance by looking at the main window.   So I asked my friend, Google, to find a simpler way.  It returned this blog about "-showlocation" flag.   Guess what...  This flag does exactly what I want.   It embeds the workspace path into the titlebar.

If you want to know how to do it, visit this wiki page, Eclipse Tips...  This page will stores useful tips on using Eclipse... Oh.. Please share your tips on this page too!
