Code Organization Issues +- **Single monolithic file**: All 325 lines of code in `main.go` +- **No separation of concerns**: UI, business logic, and utilities mixed together +- **Poor maintainability**: Difficult to navigate and extend + +### 2. Configuration and Flexibility +- **Hardcoded values**: Version number, grid columns, update interval all hardcoded +- **No customization**: Users couldn't adjust behavior without modifying code +- **Missing command-line interface**: No way to configure the app at runtime + +### 3. Error Handling +- **Silent failures**: Icon loading error commented out instead of logged +- **Ignored errors**: Many function return values discarded with `_` +- **No logging system**: Difficult to diagnose issues in production + +### 4. Testing and Quality +- **No tests**: Zero test coverage +- **No validation**: Changes could break functionality without detection +- **No CI/CD improvements**: Build process lacked quality gates + +### 5. Documentation +- **Incomplete README**: Setup instructions marked as needing overhaul +- **No changelog**: No tracking of version history +- **Missing feature documentation**: Command-line options not documented + +### 6. Code Quality Issues +- **TODO comments**: "This should be a toggle in settings" +- **Broken features**: "This doesn't actually work so far as I can tell because light theme is gone" +- **Unused code**: `getMemoryInfo()` function defined but never called +- **Code duplication**: Similar formatting logic repeated + +## Solutions Implemented + +### 1.

Configuration System + +**New `config.go` module** provides: +```go +type AppConfig struct { + Version string + GridColumns int + UpdateInterval time.Duration + HistorySize int + LogicalCores bool +} +``` + +**Command-line flags**: +- `--columns`: Grid layout columns (default: 4) +- `--interval`: Update interval (default: 2s) +- `--history`: Historical data points (default: 30) +- `--logical`: Logical vs physical cores (default: true) + +**Benefits**: +- Users can customize without recompiling +- Configuration is centralized and type-safe +- Easy to add new configuration options +- Addresses the "should be a toggle in settings" TODO + +### 3. Improved Error Handling + +**Changes made**: +- Added proper logging with `log` package +- Icon loading errors now logged instead of commented out +- CPU count errors properly handled with `log.Fatalf()` +- System info errors logged and handled gracefully +- All error returns properly checked + +**Example**: +```go +// Before: +icon, err := fyne.LoadResourceFromPath("icon.png") +if err != nil { + //log.Fatal("Could not load icon:", err) +} + +// After: +icon, err := fyne.LoadResourceFromPath("icon.png") +if err != nil { + log.Printf("Warning: Could not load icon: %v", err) +} +``` + +### 4. Comprehensive Testing + +**Test coverage added**: +- `config_test.go` - Configuration defaults +- `graphics_test.go` - Formatting functions and utilities +- `info_test.go` - System and app information + +**7 tests implemented**: +- DefaultConfig validation +- Math utility tests (abs function) +- Label formatting tests (core, util, clock) +- System information retrieval +- Application information display + +**Benefits**: +- Prevent regressions +- Document expected behavior +- Enable confident refactoring +- CI/CD quality gates possible + +### 5. Enhanced Documentation + +**README.md improvements**: +- Added comprehensive setup instructions +- Documented all command-line flags +- Included system dependency installation +- Added build and test instructions +- Updated feature list with new capabilities + +**New CHANGELOG.md**: +- Tracks version history +- Documents breaking changes +- Lists new features and fixes +- Follows Keep a Changelog format + +**Code documentation**: +- Added package-level comments +- Documented exported functions +- Included algorithm references (e.g., Bresenham's algorithm) + +### 6. User Experience Enhancements + +**Help menu with About dialog**: +- Displays application version +- Shows system information (OS, Architecture, Go version) +- Provides license information +- Easy access via menu bar + +**Better window title**: +- Dynamic version display +- Professional appearance + +### 7.

Memory Monitoring +- The `getMemoryInfo()` function exists but is unused +- Could add memory usage display similar to CPU tiles +- Would move closer to the "Windows Task Manager" goal + +### 2.
