1. **Method Signature Update**: Added `bool active` parameter to `updateHint()` method across the display driver hierarchy: - `DisplayManager::updateHint(x, y, active)` - delegates to driver - `DisplayDriverTFT::updateHint(x, y, active)` - override implementation - `DisplayDriverGFX::updateHint(x, y, active)` - override implementation 2. **Code Formatting**: `DisplayManager.h` reformatted (whitespace/comment style changes only) - **Breaking Change**: All existing `updateHint(x, y)` calls will fail to compile until updated to include the `active` parameter - **Enhanced Control**: Callers can now explicitly show/hide touch hints rather than just updating position, enabling better touch feedback UX (e.g., hide hint on touch release) - **API Consistency**: All implementations in the driver hierarchy now enforce the same signature
