“Workspace” is a product label, not a shared technical contract. In a browser it commonly refers to web pages or saved resources. On the desktop it may refer to application windows, launchable files, or a screen arrangement. Choose by the objects you need to recover.
Identify the managed object
A browser workspace can contain tabs, tab groups, bookmarks, or saved web resources. Switching it may change the contents inside one browser window while the macOS window itself remains the same. Browser profiles add another identity boundary for cookies and account state.
A desktop workspace can organize the browser window together with an editor, document, terminal, or Finder window. Some products launch resources; others find windows that are already open; layout tools move and resize windows. These behaviors are independent even when products use the same word.
Ask what “return” means
Do you need to reopen URLs after a restart, return to currently open windows, or recreate exact screen geometry? A tool may support one without the others. Check whether data is local or synced, whether app state is restored, and what happens when a resource is renamed or a window is closed.
Combine layers deliberately
Use a browser workspace for the web set and a desktop organization method for the cross-app working set. Do not expect the outer layer to know which internal browser workspace is active. Wallo associates existing macOS windows with goals and tasks; it does not store tabs, reopen URLs, or restore layouts.
