Tiles Mode
This page contains options that control the appearance of the file display in 
Tiles mode. The options in the Size and Layout section are:
  - Tile size: This specifies the size of individual tiles 
  (or more accurately, of the text part of individual tiles). It is given as the 
  number of characters wide and the number of lines of text high. 
  
 - Tile spacing: This is the spacing between tiles 
  (horizontal x vertical), in pixels. 
  
 - Expand tile with focus if needed: When a tile has the 
  input focus, it will be expanded to overlap other adjacent tiles if its label 
  is bigger than the size allowed in the Tile size setting. 
  This lets you read the full name of the selected item when it may otherwise be 
  clipped. This option is overridden if visual styles are enabled for file display 
  items. 
  
 - Vertical layout: Normally the Tiles display has a 
  horizontal layout - tiles are drawn from left-to-right, top-to-bottom, and if 
  a scrollbar is needed the list scrolls vertically. With this option on, the 
  layout is switched to a vertical one - tiles go top-to-bottom, left-to-right, 
  and scrolling is horizontal, similar to List mode. 
 
 
You can optionally have Tiles mode also display thumbnails for files - the 
options that control this are:
  - Show Thumbnails in Tiles mode: Turn this on to enable the 
  display of thumbnails in tiles mode. Thumbnails are generated subject to the 
  settings on the Thumbnails 
  page. 
  
 - Thumbnail size: Specifies the size of thumbnails in 
  pixels. 
  
 - Show file type icon in tile: Because the thumbnail 
  replaces the display of the normal file icon, this option lets you display a 
  small version of the icon in the bottom corner of the tile. Either the frame 
  or fill options (below) must be turned on for this to work - it's disabled 
  otherwise, because the file type icon would end up floating in space. 
  
    - Hide file type icon if type not registered: With the 
    above option on, the file type icon will not be shown if the file type is 
    not registered. This mostly applies to image files that may have no file 
    extension - Opus is still able to display thumbnails for them as it looks at 
    the file contents to determine their type, but there would be no valid icon 
    registered in the system that could be shown. 
 
   - Show thumbnail borders: This option makes Opus display a 
  frame around thumbnails in the tile. You can also specify a Fill 
  color when the thumbnail is framed. 
 
 
Tiles can be displayed with or without frames, and with the interior filled 
or unfilled. The options for Frame and Fill are:
  - Show tile frames: This option displays a frame around 
  each tile. You can select two colors for the frame - the top and left edges 
  use one, and the bottom and right edges use the other. 
  
 - Fill tile interior: This option fills the tile's 
  background. You can select two colors - if they're different, a gradient fill 
  will be performed.
