A notable shift was toward modularity. Instead of all-or-nothing bundles, creators offered interchangeable icon sets, wallpapers, and sound packs. Users could mix a minimal icon set with a vivid wallpaper, or apply a high-contrast text style without losing their favorite ringtone. That modular approach respected the C7 owner’s desire for fine-grained customization and reduced compatibility issues between themes and system updates.
