Voltius v0.18.0

Added

• Pasting a host into another vault now carries its key and identity across, so
  the pasted host still connects instead of landing without credentials.
• useT and useSessionById are available to plugins from @voltius/ui.

Fixed

• Renaming a folder moved it into the Personal vault. Any folder kept in another
  vault was silently relocated, taking everything filed in it along.
• Moving a key, identity, connection or folder to another vault unpinned it, as
  did renaming or reparenting a folder.
• Members of a team vault received a passphrase-protected connection key without
  its passphrase, so they could not connect. Both the current and the legacy
  storage paths now publish it.
• The folder picker in the host, serial-host, key and identity editors offered
  every page's folders, so a host could be filed into a keychain folder — the
  editor then showed it in a folder its own page does not list, leaving it
  sitting unfiled at the top level. Creating a folder from the key or identity
  editor made a host folder for the same reason.
• Pasting a copied object no longer appends "(copy)" when nothing of that name
  is there to collide with.
