**io.Connect Browser 4.4** is out, bringing new options for saving window contexts in Layouts, persisting user-selected themes via the App Preferences API, and listening for Workspace tab reorder events. Full changelog: [io.Connect Browser 4.4](https://docs.interop.io/browser/getting-started/changelog/4-4/index.html) ## [Saving Window Contexts in Global Layouts](https://docs.interop.io/browser/getting-started/changelog/4-4/index.html#new_features-interopiobrowser-saving_window_contexts_in_layouts) When saving a **Global Layout** programmatically, you can now instruct the platform to persist the context objects of individual io.Connect Windows. These are the contexts set via the `setContext()` method of a `WebWindow` instance. This is controlled through the new `saveWindowContexts` property of the `NewLayoutOptions` object. If a Browser Client has subscribed for Layout save requests via `onSaveRequested()` and the event handler returns a context object, that context takes precedence over the context set via `setContext()`. If `ignoreContexts` is set to `true`, `saveWindowContexts` is ignored.

When saving a Workspace Layout, use the `saveWindowContexts` property of the `WorkspaceLayoutSaveConfig` object passed to `io.workspaces.layouts.save().`You can also use `saveLayout()` on a `Workspace` instance when saving an open Workspace as a Workspace Layout. If a Browser Client has subscribed for Layout save requests via `onSaveRequested()` and the event handler returns a context object, that context takes precedence over the context set via `setContext()`.

This enables theme selection to be synchronized across different devices and browser sessions for the same user. When using a local App Preferences store, themes continue to be stored in browser local storage as before.

These events are triggered only when dragging a tab to a different position without removing it from its current container. At API level, you can subscribe with: - `onWorkspaceTabReordered()` for Workspace tab reorder events; - `onWindowTabReordered()` for window tab reorder events. Tab reorder events are also available on: - `Workspace` instances via `ontabReordered()` and `onWindowTabReordered()`; - `WorkspaceWindow` instances via `ontabReordered()`.
