Floatrix includes all of Matrix's settings with the exception of rows and columns.
Row width and height values are set to 200px and 300px respectively. These values can be changed to accomodate thumbnail widths and the vertical space required when displaying item details (album owner, date, count, ratings, etc.). Content that overflows the div container's dimensions is hidden.
In addition to item container dimensions, Gallery administrators may also set the number of items per page to display.
