When added a custom extension via 'initDevtools' method, the extensions are working correctly to the moment when you need to refresh your site. After refreshing, only the default version of Pixi DevTools are working, like the custom ones were never there. The only way to use them again is to recompile the project.
I tried to add my custom extensions to the source code of the Pixi DevTools, and make the build from it. This approach works well; the custom extensions are working, and they are visible after refresh.
