Light and Dark Mode Support for the Default Theme

📋 Summary

Add full light and dark mode support to the default LaunchBox theme, with an option to switch manually or follow the operating system theme setting.

❗ Problem

LaunchBox currently has some light theme support in certain areas, such as settings, but the main application does not have a full light mode.

This means:

• The main program remains visually inconsistent with lighter UI areas

• Users who prefer light themes do not have a complete built in option

• LaunchBox cannot match the user’s Windows light or dark mode preference

• Users must rely on custom themes for a basic light mode experience

💡 Proposal

Add full theme mode support to the default LaunchBox theme:

• Light mode

• Dark mode

• Follow system setting

This could be exposed as an appearance option, for example:

• Default Light

• Default Dark

• Use Windows Theme Setting

The selected mode should apply consistently across the main application, settings, dialogs, and core LaunchBox UI.

🧩 Use Cases

• A user prefers a brighter UI during daytime use

• A user wants LaunchBox to match their Windows appearance setting

• Users with visual preferences or accessibility needs can choose the theme that works best for them

• LaunchBox feels more consistent across main views and settings

📦 Benefits

• Provides a complete built in light theme option

• Improves visual consistency across the application

• Aligns LaunchBox with modern desktop app behavior

• Reduces reliance on third party themes for basic appearance preferences

• Improves accessibility and comfort for users with different display needs

⚠️ Considerations

• Needs consistent styling across dialogs and embedded UI areas

• Should preserve existing dark theme behavior by default

• “Follow system” should update reliably when the OS theme changes
