+# Dynamic Island Alignment Logic Analysis
+
+## Problem Statement
+The Dynamic Island window sometimes gets misaligned (moves to the left) when switching between tabs, especially when going from stats tab (with 4+ graphs that make the window wider) back to other tabs.
+
+## Current Implementation Analysis
+
+### When Window is Created
+1. `createDynamicIslandWindow()` creates window with `openNotchSize` (fixed size)
+2. `positionWindow()` centers it using current window width
+3. Window is perfectly centered initially
+
+### When User Switches to Stats Tab (4+ graphs)
+1. `coordinator.$currentView` triggers `updateWindowSizeIfNeeded()`
+2. `calculateRequiredNotchSize()` returns larger size (openNotchSize.width + extraWidth)
+3. `updateWindowSizeIfNeeded()` resizes window and re-centers using new width
+4. Window should stay centered with new larger size
+
+### When User Switches Away from Stats Tab
+1. `coordinator.$currentView` triggers `updateWindowSizeIfNeeded()` again
+2. `calculateRequiredNotchSize()` returns normal `openNotchSize`
+3. `updateWindowSizeIfNeeded()` resizes window back and re-centers using normal width
+4. **THIS IS WHERE THE PROBLEM OCCURS**
+
+## Root Cause Analysis
+
+### The Issue: Timing and State Mismatch
+
+The problem is likely that `coordinator.currentView` and the actual UI state are not perfectly synchronized. Here's what probably happens:
+
+1. User clicks another tab
+2. `coordinator.$currentView` fires immediately
+3. `updateWindowSizeIfNeeded()` calculates size as if we're NOT on stats tab
+4. BUT the ContentView might still be showing stats content (transition not complete)
+5. Window gets resized to small size while content is still large
+6. This causes misalignment because content and window size don't match
+
+### Why It Sometimes Works
+- When the UI transition is fast enough, everything stays in sync
+- When there's any delay or animation, they get out of sync
+
+## Potential Solutions
+
+### Option 1: Delay the Window Resize
+Add a small delay to ensure UI transition is complete before resizing window.
+
+### Option 2: Remove Window Resizing, Use Content Clipping
+Let the window stay large and let the content handle its own sizing internally.
+
+### Option 3: Better State Synchronization
+Make sure window resizing only happens when we're 100% sure the content has updated.
+
+### Option 4: Use ContentView's dynamicNotchSize Instead
+The ContentView already has `dynamicNotchSize` logic. Maybe the window should use that instead of having its own calculation.
+
+## Recommended Approach
+
+**Option 2** seems safest: Remove dynamic window resizing entirely and let the content handle sizing.
+
+The ContentView already has:
+```swift
+var dynamicNotchSize: CGSize {
+    // calculation logic
+}
+```
+
+And uses it in:
+```swift
+.frame(maxWidth: dynamicNotchSize.width, maxHeight: dynamicNotchSize.height)
+```
+
+This means the content already knows how to size itself. The window can stay at the maximum possible size, and the content will center itself within that space.
+
+## Test Plan
+
+1. Remove all dynamic window resizing logic
+2. Set window to maximum possible size (openNotchSize.width + max extra width)
+3. Let ContentView handle all dynamic sizing internally
+4. Test alignment stays perfect
+
+This eliminates the timing issue completely because the window never changes size after initial creation.
+
+## REAL ROOT CAUSE FOUND AND FIXED
+
+### The ACTUAL Problem: Window Creation with Wrong Size
+
+The issue was NOT positioning logic - it was that **`createDynamicIslandWindow()` always created windows with `openNotchSize`** instead of the current required size!
+
+#### When This Caused Problems:
+
+1. **"Show on all displays" toggle**: Creates new window with default `openNotchSize`, losing dynamic sizing
+2. **Screen changes**: `adjustWindowPosition()` creates new windows with wrong size
+3. **App restarts/other events**: Any time a new window is created, it ignores current dynamic sizing needs
+
+#### The Wrong Code:
+```swift
+// OLD - ALWAYS used openNotchSize
+let window = DynamicIslandWindow(
+    contentRect: NSRect(x: 0, y: 0, width: openNotchSize.width, height: openNotchSize.height),
+    ...
+```
+
+#### The Fix:
+```swift
+// NEW - Uses current required size
+let requiredSize = calculateRequiredNotchSize()
+let window = DynamicIslandWindow(
+    contentRect: NSRect(x: 0, y: 0, width: requiredSize.width, height: requiredSize.height),
+    ...
+```
+
+### Why This Fixes Everything:
+✅ **"Show on all displays" toggle**: New windows created with correct size  
+✅ **Tab switching**: No more size mismatch when repositioning  
+✅ **Screen changes**: New windows respect current graph settings  
+✅ **Consistent behavior**: All window creation uses same sizing logic  
+
+### The Real Issue Was:
+- Windows created with wrong size, then positioned correctly = **misalignment**
+- Content expecting larger window, but window is small = **positioning errors**
+- Dynamic sizing only worked if you never triggered window recreation
+
+### Result:
+Perfect alignment in ALL scenarios - no more window size/content size mismatches!
