v0.12.0 changes what happens after a mistake and after a link is clicked. History survives, new prep starts private, and the Library can reopen a specific entry or page.
History
The History panel keeps up to 100 content actions per person. Undo and Redo survive reloads, reconnects, sleep and server restarts. A GM can inspect another player's history but can only reverse their own work.
History includes Library and page edits, access changes, placeables, scene changes and drawings. Rich-text typing groups into an edit, while a changed or missing target leaves the action blocked instead of applying half of it.
New prep starts private
New notes, journals and other preparation entries start GM-only unless their type declares a shared default. Existing entries keep their current access. Tokens and scene objects can keep their own table-visible defaults, and content packs keep the permissions they explicitly requested.
Readers also stop receiving the sharing grants of other people. The GM and the entry owner can manage access; other readers see only the grant that applies to them.
Copy a Library link
Copy link opens a named world and selects its Library entry. Copying a page link selects the page as well. The target can survive sign-in, a closed Library or a reload, and browser back and forward revisit earlier selections.
Missing, private or deleted targets use the same unavailable state. A link for another world offers that world's launch instead of switching worlds silently.
