How do I remove sidebar from Devonthink 3 pro. Previous versions allowed for removal or repositioning lower in the Finder window
The sidebar can be only shown/hidden, both in version 2 & 3. See e.g. toolbar item to toggle it.
The appearance and position of the Sorter can be customized via Preferences > Sorter.
Many thanks. Helps when you know the correct name for the bits and pieces:)
