MuK Preview enables support to preview binary files directly in
Odoo. It adds a button to the binary field, which opens a file
preview dialog. The preview can be easily extended by adding new
Preview to the registry. Besides adding the preview button to
existing binary fields, there is a new widget
binary_preview
which can be used to display the preview directly in the form view.
Furthermore it is possible to preview PDF and text reports directly
from the sidebar.
