Those "fake screenshots" to demonstrate your idea indeed look visually appealing.
On second thought, I would be interested if this (a graphical alternative to the current implementation) is your main motivation, or if those changes might address usability concerns you might have experienced.
When looking at those request-based selections of setup options (which use level editor style radio buttons), I am thinking about how these UI elements would be used. In the level editor, it is clear that you would just point and click with the mouse, as the level editor's user interface is clearly mouse driven. (Even though there are a number of key shortcuts here and there, it would not be possible to use the level editor without a mouse (or any other pointing device -- for example, the level editor can be used on touch devices when using a specially prepared graphics set to make it easier to select game elements from the element palette).
On the other hand, all R'n'D screens other than the level editor are designed to be fully usable with either a keyboard or a two-button joystick (or game pad), and do not contain most of the more sophisticated "gadgets" (graphical user interface elements like select boxes, check boxes, radio buttons and others).
While it would principally be possible to use the proposed new request dialogs just as before (with keyboard or joystick), it would add another break in the user interface. As radio buttons currently cannot be selected by clicking on the radio button text (as it is possible with all setup options now), but only on the button itself, it would make things harder to use, especially on a mobile device.
Another question might arise what should happen when there are more option than fit to the request window. Add a scrollbar? How wide should the scrollbar be then? As R'n'D currently does not support swipe gestures to scroll the screen, it should at least be as wide as the current scrollbar in the setup menu, which might look weird for a dialog request with small buttons and small text.
So for now, it seems that there would be more disadvantages than advantages for the proposed change.
Any other comments or ideas on this?
