Thanks for getting back to us on this.
As a matter of fact, if you right-click on the .Model project, and select Build, this will rerun all the generators that are included in the model build (via the corresponding generator property), which is basically that "ReGenerate Everything" option you were looking for. You should see all the generators being run in the Output window.
Now, on the issue with the main menu, it looks like the <module> elements, where your views are defined in the model may have no "name" attribute, which makes them not being generated for the main menu, since it's organized by the modules.
As a workaround, I'd recommend adding the name to your modules, which would also help you keep the generated views, data objects and other artifacts organized. But if you really don't want the named module, you can generate the main menu, revert back to no-name, and use the generated menu as custom code in a separate .ts file.
On our end, we can update the generator to place all such views from the default module under some fixed menu, such as 'Views'.
Please let us know if this works for you.
