Run multiple Copilot chats side by side. Or any editor layout you need — instantly.

ext install waldek.tiler

Or search "Tiler" in the VS Code Extensions view (Cmd+Shift+X).

Cmd+K 4    →    2×2 grid (perfect for 4 Copilot chats)
Cmd+K 2    →    side by side
Cmd+K 1    →    back to single pane

That's it. Muscle memory in 30 seconds.

Command Palette only (for when you need something specific):

• 2×1 — Stacked (2 rows)
• 1×3 — Three columns
• 3×1 — Three rows

Note: On Windows/Linux, use Ctrl+K instead of Cmd+K.

The killer feature. Run multiple AI agents simultaneously:

1. Cmd+K 4 for a 2×2 grid
2. Open 4 Copilot chat sessions
3. Drag each to a different pane
4. Ask different questions in parallel
5. Watch your AI army work

Side-by-side comparison of implementations:

• Original vs. refactored
• Your code vs. reference implementation
• Multiple related files

When you're touching several files at once, Cmd+K 4 keeps them all visible without constant tab switching.
