When developing large applications in Reactive, it is not a good practice to have all screens in the same module, otherwise its size grows considerably, taking a lot of time to open and to deploy. In those situations, it is common to split the screens through different End-User modules.
At this moment for Reactive applications, it is not possible to control the module name in the URL, without being through changing the module name. This is not ideal, because the module respects a naming convention according to the factory governance, for instance <Business Application>_<MainConcept>. Besides the name the module appears in the URL is usually lower-case whereas module names are usually camel-case.
Being that said, I think it would be nice to have the possibility to define the module SEO name, just like it is done for pages in Reactive Applications. This is a feature from Traditional Web that does not exist in Reactive and it's unfortunate that one has to change the name of the module from MyApp_Support to support, for this purpose, going against our governance and architecture naming convention.
