The main part of the Fixture Share is the file browser. It is divided into three columns. They are displayed below the search area.
The left column is a list of all the Manufacturers. Selecting one displays all the Fixtures from the manufacturer in the center column. Selecting a fixture lists all the Mode options in the right column. The amount of DMX channels (called footprint) and the amount of Instances used by the mode is listed below the mode name.
