+# #2771 Fix missing macOS tiling menu options on zoom button
+
+### What
+Restores the native macOS tiling hover menu (including "Move & Resize", "Fill & Arrange", and "Enter Full Screen") when hovering over the window's green zoom button.
+
+### Why
+The window was explicitly marked as non-movable (`nswindow.movable = NO`), which caused macOS to disable part of the native window-management menu. In addition, the window was not explicitly marked as participating in Split View.
+
+### How
+Updated `3rdparty/qwindowkitty/src/core/contexts/cocoawindowcontext.mm`:
+
+1. Removed `nswindow.movable = NO`.
+2. Added `NSWindowCollectionBehaviorFullScreenPrimary` to the window's collection behavior so it participates in macOS Split View and tiling.
