We've added a centralized configuration system that reads from ~/.porthole.yaml, allowing you to persist preferences for display filters, themes, animations, and polling intervals. This update replaces previous hardcoded defaults with configurable settings and includes validation logic to ensure safe runtime behavior. Users can now easily toggle system processes, adjust port ranges for safety, and customize their TUI experience, with full support for overriding these via CLI flags or the new 'a' keybinding.
