The first official release of the DebugPress plugin is now available for download from WordPress.org. You can install it directly from the WordPress plugins panel.
The first plugin version is more or less the same debugger from the GD Press Tools Pro plugin, with the codebase rewritten and modernized to use namespaces and auto-loading. But, it also enhances some of the features, including the ability to track both successful and failed AJAX calls, and the enhancements for the AJAX tracking to use debug log to mark each call errors.
Test out the new release, and if you have any suggestions, let me know, through comments, or directly on GitHub.
