Even if I would try to build an app (which I’m currently doing) - there is no real documentation for code hooks, template overriding or such things. So, I’m still in the dark to how I could replace for example the whole userBar.phtml, which I did before easily with the template editor in v4. Are there any documentation how I can change the whole template file, without having to add template hooks (which only has 4 hook types but no replace)?
