UI Consistency and User-Selectable Themes (Dark/Light Mode)

SM6KZW

I would like to propose an update to the SmartSDR UI to address visual inconsistency and improve accessibility.

While the main SmartSDR interface sports a modern dark theme, several essential sub-windows, most notably the Global Profiles manager, revert to standard bright white Windows dialogs.

This creates a jarring visual discontinuity. My workflow relies on keeping the Profiles window open constantly for quick switching between operating modes. Having a bright white window floating next to the dark panadapters creates significant glare and eye strain, especially in a dimly lit shack. It also makes the software feel less cohesive.

I suggest implementing the following:

1. Unified Theming: Ensure that all child windows (Profiles, Settings, etc.) inherit the theme of the main application.
2. User Choice: Allow users to toggle between a "Dark Mode" and a "Light Mode."
3. System Sync: Ideally, add an option for SmartSDR to respect the Windows System Theme preference automatically.

Offering theme choices is not just about aesthetics; it is an accessibility requirement. While I prefer a dark theme, many visually impaired users or those with astigmatism require a light theme for better legibility. Giving users control over the UI appearance would greatly enhance the usability and professional feel of the software.
