Display Game Ratings as Percent or Other Formats

📋 Summary

Add native options in LaunchBox and Big Box to display game ratings as a percentage (and optionally other formats), without changing how ratings are stored or entered.

❗ Problem

LaunchBox currently displays ratings primarily as a 5 star value. This works well, but it limits theme creators and UI customization:

• Themes often need ratings shown as percent, out of 10, or text

• Converting star values inside XAML usually requires heavy triggers or visual hacks

• These conversions can add overhead in wheels and large lists, causing lag

• Plugins can solve it, but add complexity and reliability concerns for both creators and users

Theme creators need a lightweight, native way to render ratings in different formats.

💡 Proposal

Introduce display format options for ratings, handled by the core logic engine:

• Keep rating entry and storage unchanged

• Add new display outputs such as:

  • Percent (0 to 100%)

  • Out of 10

  • Optional text labels (e.g., Mixed, Good, Excellent)

• Expose these as theme friendly fields so creators can use them without custom conversion logic

📦 Benefits

• Gives theme creators more flexibility without hacks or plugins

• Reduces UI overhead from XAML conversions and triggers

• Improves performance in wheels and large views

• Keeps the existing rating system intact while expanding presentation options

💡 Notes

• Default behavior should remain 5 star display

• Mapping rules for text labels could be configurable or fixed

• Percent and out of 10 can be derived directly from the existing 0.1 to 5.0 rating value
