Workspaces, folders and custom domains, rebuilt

Workspaces, folders and custom domains were rebuilt on one access rule: a document has one access level at every address it has, on markdrop.in and on your workspace's domain alike.

• Share a folder with a single link. People see only the items they can already open.
• Renamed addresses send readers to the new one, and old addresses are never handed to someone else.
• Custom domains are re-checked every day. A domain whose DNS no longer points at Markdrop stops serving after three days of failed checks.
• Editors and workspace members can replace a file from the viewer.
• AI apps can list workspaces and folders, file documents, create folders and move items, and the CLI can upload straight into a folder.

Existing workspace links keep working.
