## 🚀 Quick Start

### Installation
The new features are automatically available when you import pomice:

```python
import pomice

# All new features are now available
history = pomice.TrackHistory()
stats = pomice.QueueStats(queue)
pomice.PlaylistManager.export_queue(...)
filtered = pomice.TrackFilter.by_author(tracks, "Artist")
```

### Basic Usage Example

```python
import pomice
from discord.ext import commands

class Music(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.history = pomice.TrackHistory(max_size=100)

    @commands.Cog.listener()
    async def on_pomice_track_end(self, player, track, _):
        # Add to history when track ends
        self.history.add(track)

    @commands.command()
    async def stats(self, ctx):
        """Show queue statistics."""
        stats = pomice.QueueStats(ctx.voice_client.queue)
        summary = stats.get_summary()

        await ctx.send(
            f"**Queue Stats**\n"
            f"📊 Tracks: {summary['total_tracks']}\n"
            f"⏱️ Duration: {summary['total_duration_formatted']}\n"
            f"📡 Streams: {summary['stream_count']}\n"
            f"👥 Unique Requesters: {summary['unique_requesters']}"
        )

    @commands.command()
    async def history(self, ctx, limit: int = 10):
        """Show recently played tracks."""
        recent = self.history.get_last(limit)

        tracks_list = '\n'.join(
            f"{i}. {track.title} by {track.author}"
            for i, track in enumerate(recent, 1)
        )

        await ctx.send(f"**Recently Played:**\n{tracks_list}")

    @commands.command()
    async def export(self, ctx):
        """Export current queue."""
        pomice.PlaylistManager.export_queue(
            ctx.voice_client.queue,
            f'playlists/{ctx.guild.id}.json',
            name=f"{ctx.guild.name}'s Queue"
        )
        await ctx.send('✅ Queue exported!')
