I have followed this example to enable dynamic form processing for the app, so unlimited ui files can be used and swapped without compiling. It works, but the binary is over 1mb since it has to precompile the form at every startup, and I don't think getting portrait support for 1mb space is so needed. It even needs to restart app to switch form, so just doing another QRadio version only with portrait is a lot better in my opinion. Autorotation is out of scope, there is no equivalent of a ProxyLayout with Designer and QRadio ui needs a lot of changes to switch orientation.

What this app really need now is getting tested and voted.
