Subject locator previews
Wandora's Traditional topic panel views subject locator resources if the View subject locators option is enabled. The menu option is available at View > Traditional w ... > View subject locators. Also, right to the subject locator field is an icon button toggle to switch subject locator previews on and off. Wandora doesn't view subject locator resources by default.
When subject locator preview is enabled, Wandora checks if there is a valid subject locator URI and tries to figure out mimetype for the subject locator resource. Wandora supports both external resources and internal data URI resources. Once the mimetype is resolved, Wandora chooses a viewer for the resource and initializes the viewer.
