 # SimpleLogger
 
-Multi-level logging system for Godot with timestamps and file persistence.
+Lightweight logging system for Godot 4.5+
 
 ## Features
 
-- 5 log levels: TRACE, DEBUG, INFO, WARN, ERROR
-- Full and abbreviated function names
-- Optional timestamps
-- File logging with auto-directory creation
-- Configurable argument separator
+- 5 log levels (TRACE, DEBUG, INFO, WARN, ERROR)
+- Caller script tracking
+- Script filtering (blacklist/whitelist)
+- Performance profiling
+- Optional file persistence
+- Configurable timestamps and separators
+
+## Quick Start
+```gdscript
+Log.i("Player spawned")
+Log.d("Health:", player.health, "Position:", player.position)
+Log.e("Failed to load resource", path)
+```
+
+Output:
+```
+[12:34:56][player       ][INFO  ]: Player spawned
+[12:34:56][player       ][DEBUG ]: Health: 100 Position: (0, 0)
+[12:34:56][resource_load][ERROR ]: Failed to load resource res://missing.png
+```
+
+## API
+
+### Log Levels
+
+| Full | Short | Use case |
+|------|-------|----------|
+| `trace()` | `t()` | Granular debugging |
+| `debug()` | `d()` | Development info |
+| `info()` | `i()` | General events |
+| `warning()` | `w()` | Potential issues |
+| `error()` | `e()` | Failures |
+
+### Filtering
+```gdscript
+Log.mute("chunk_generator.gd")
+Log.unmute("chunk_generator.gd")
+
+Log.set_blacklist(["map.gd", "noise.gd"])
+Log.set_whitelist(["player.gd", "enemy.gd"])
+Log.clear_filters()
+```
+
+### Performance
+```gdscript
+Log.time_start("pathfinding")
+# ... code ...
+Log.time_end("pathfinding")
+# Output: [DEBUG ]: PERF pathfinding 12.34ms
+```
+
+### Separator
+```gdscript
+Log.set_separator(" | ")
+Log.set_separator(" -> ", true)  # one-time only
+```
 
 ## Properties
 
-| Property | Type | Default | Description |
-| --- | --- | --- | --- |
-| `current_log_level` | LogLevel | DEBUG | Minimum log level to display |
-| `enable_timestamp` | bool | true | Add timestamp to messages |
-| `save_log` | bool | false | Save logs to file |
-| `separator` | String | " " | Separator between arguments |
-| `folder` | String | "" | Directory for log files |
-| `log_filename` | String | "addons/Logs/data.log" | Log file path |
-
-## Usage
-
-```gdscript
-# Full names
-Log.trace("message", var1, var2)
-Log.debug("message", data)
-Log.info("message")
-Log.warning("message")
-Log.error("message", error_code)
-
-# Abbreviated
-Log.t("message", var1)
-Log.d("message", data)
-Log.i("message")
-Log.w("message")
-Log.e("message")
-
-# Custom separator
-Log.set_separator(", ")
-Log.info("a", "b", "c")  # [INFO  ]: a, b, c
-
-# One-time separator
-Log.set_separator(" | ", true)
-Log.info("x", "y")  # [INFO  ]: x | y
-Log.info("a", "b")  # [INFO  ]: a b
-```
-
-## Output Format
-
-```
-[HH:MM:SS]|[LEVEL  ]: Message   # With timestamp
-[LEVEL  ]: Message               # Without timestamp
-```
+| Property | Default | Description |
+|----------|---------|-------------|
+| `current_log_level` | DEBUG | Minimum level to display |
+| `enable_timestamp` | true | Show timestamps |
+| `enable_caller` | true | Show calling script |
+| `save_log` | false | Write to file |
+| `filter_mode` | BLACKLIST | Filter behavior |
+| `folder` | "" | Log directory |
+| `log_filename` | "addons/Logs/data.log" | Log file path |
