I have a few improvements which would make Cuba/J-Mix for me a more complete RAD-Tool. There could a few more screens/wizards to give it a rich feel and make wizards for repetitive tasks.
- When using a table/datagrid/etc.in editable mode there much time spend on creating custom generated columns. Sometimes it is as simple as creating a dropdown.
- Easily creating ordered items (in datamodel aswell as in the screens).
- When defining a new project it would be nice for new users to select a quickstart like the PetClinic app or maybe a new sample project.
- New screens for:
** Login screen and register screen in one
** Password reset
** Master detail with editable grid
** More types of main screens
** Add-ons like chats, maps etc.
