~~Title: Title Bar~~
<pageheader/>

  * **Custom title**: Lets you completely configure the string used in the  title bar. If you turn this option on, the text you provide will be used to generate the title string. See below for more information.
  * **Display full path**: Turn this option on to display the full path to each file in the title bar of the viewer window. If turned off, only the filename will be shown. 
  * **Move toolbar into the window title bar**: The viewer's toolbar will be displayed as a custom window title bar, rather than appearing below the standard title bar. Any blank spaces in the toolbar (e.g. Spacer buttons) can be used to drag the window. The window icon (top-left) can also be used to move the window if <kbd>Shift</kbd> or <kbd>Ctrl</kbd> are held down (in case there's nowhere on the toolbar that can do it). The status bar (if turned on) can also be used.

==Custom title bar==

You can use several special "tokens" in the title string to insert various pieces of information:

|**%P**|full path of the currently viewed image|
|**%N**|name of the current displayed image|
|**%R**|drive root of the current image|
|**%E**|displays * if the image's metadata has been modified and not saved|
|**%I**|current image's index (number) in the list of images|
|**%O**|total number of images in the list|
|**%W**|width of the current image|
|**%H**|height of the current image|
|**%D**|depth of the current image (bits per pixel)|
|**%M**|current image's dimensions|
|**%S**|file size on disk|
|**%A**|image load time|
|**%F**|folder name|
|**%C**|collection name if current image is [[:additional_functionality:viewing_images:image_marking|marked]]|
|**%L**|any [[:file_operations:labels|labels]] assigned to the current image|
|**%T**|complete original title (useful for simply adding a prefix or suffix to the title)|
|**%Z**|zoom (magnification) level|
|**%G**|gamma correction|
|**%U**|current selection area|
|**%%%%%%**|insert a literal %  character|
|**%!**|hide empty blocks within %!...%! (see below)|

The `%!` code is special in that it should be used in pairs around the things you want to hide. They will be hidden if all tokens within the block expand to empty values.

Consider `%!Dimensions: %W x %H%!`, for example: If `%W` and `%H` (width and height) are unavailable (e.g. because the  viewer isn't displaying an image) then this will output nothing at all instead of a meaningless //"Dimensions: 0 x 0"//.
