Is Multi Layout Manager safe?

Multi Layout Manager saves open tab URLs and window metadata into local browser storage when you save a layout.

When you use the extension UI to save a workspace layout, it reads the open tabs in normal browser windows and records each tab's URL, index, active state, and pinned state. It also stores window metadata such as size, position, focus, incognito flag, and type in chrome.storage.local so the layout can be restored later.
