Problem Description

The current theme selection dialog uses a long vertical list of radio buttons, but it does not contain all possible permutations of the base themes – for example, it lacks the "System dynamic and black"

Issues with current implementation:

• Visual Clutter: Overwhelming list of items to scroll through.
• Redundancy: Basic choices (Light / Dark / System) are mixed together with modifiers (High Contrast, Pure Black, Dynamic Colors).
• Poor UX: Choosing a theme requires reading through 10+ options.

Proposed Solution

Redesign the theme selection layout using a Segmented Control + Sub-options/Toggles approach:

1. Top Control (Segmented Buttons):

   • A clean horizontal group to pick the primary state: System | Light | Dark

2. Secondary Options (Toggles / Dropdowns below):

   • Use pure black dark theme (Toggle switch)
   • Contrast level (Dropdown or Segmented control: Standard / Medium / High)
   • Dynamic colors / Material You (Toggle switch)

Here is what it could look like:

Alternatives Considered

Keep the current dialog layout but add missing combinations to the list, such as the "System dynamic and black" option.
