Chrome extension is available in the github downloads area now. The extension uses devtools APIs (but no longer experimental) which are currently only ready in the chrome dev channel version. However the plugin should be stable, so as chrome moves into beta and then stable release I believe it will continue to work.
Note that when you install the extension, it will ask for permission for all your web pages (although it does nothing with that data; but it's the only way to read the wicketsource="" attributes). If there's enough interest, I can try making a version that only needs permissions for localhost and shuts itself off for other websites. That does limit remote debugging uses a bit though. Jenny
