Do you have any future plans?

Sure:

• A lot more automatic tests.
• Combine the bars with a graph of CPU usage etc.
• It would be nice if the instrumentation feature would work in older versions of Java than 5. To do this, we could use the Java Platform Debugger Archtecture (JPDA). Not a high-priority issue, since everybody will probably use Java 5 anyway when I get this working...
• Export displayed graph data to a "comma-separated values" file, for later import into a spreadsheet.
