GWT Super Dev Button is a Chrome extension designed for GWT developers who use Super Dev Mode. This small "page action" button enables users to view all modules on a specified codeserver and compile them without the need to add bookmarklets each time for each module. The "Module" dropdown displays all available modules on the specified code server, and users can reload the modules by changing the code server URL.

One of the most useful features of GWT Super Dev Button is the "Compile" button, which remembers the code server URL when pressed. It is worth noting that users may need to reinstall the extension to make the Hot-Key work. The developer has also provided updates to improve the user experience, including fixing layout issues, disabling the compile button, and making the popup dialog more compact. If you encounter any bugs, the developer encourages you to submit a bug report.
