Good for safe scene tree manipulation, avoiding "node doesn't exist yet" errors. • await: Godot 4's async/await pattern. Replaces yield. Used for non-blocking waits (signals, timers, functions returning Future). Keeps main thread responsive. • Signals: Native Godot event system. Decouples systems, enables reactive UI/engine updates without polling. Essential for multi-tab state management. • Threading (Thread/Callable.bind()/@thread_sync): For heavy CPU tasks (AI inference, network I/O) that shouldn't block the main thread. • Process Modes (PROCESS_MODE_ALWAYS, INHERIT, PAUSE): Controls when nodes update across different UI states (modals, hidden tabs). • State Machines / Context Managers: Managing tab switches, engine lifecycles, and background vs active states without race conditions.
