When toggled on, only the image filename will be displayed in the window's title bar.

If toggled on, new catalogs will default to having the Burn Mapping On Save option turned on (Catalog->Burn Mapping On Save). With the Catalog->Burn Mapping on Save option turned on, images saved via File->Export will have their current view mapping burnt into the pixel values before writing to disk. This is useful if you want to share your renders from "it", especially in 8bit oriented file formats like png and jpeg.

The remap menu shows the color space that your image is in. Typically this would be linear for rendered images and sRGB for 8 bit image files. By default "it" chooses the image space of the image and when it does this the image space is preceded by a *. You can use the menu to override "it"'s choice (the * indicator will go away)
"it" supports view mapping output images to accommodate your workflow of choice using the OpenColorIO system (http://opencolorio.org). Your view mapping defaults can be set for images rendered to "it" as your framebuffer (regardless of bit depth) or for imported images (with different mapping for different types, if necessary).
There are several important things to remember about remapping:
Remapping is applied only for viewing files. It is not burned in. There is a prefence for controlling whether the mapping is applied when images are saved. This option is controlled on a per-Catalog basis so it is important to note that when changing this preference it will only affect new Catalogs. Each Catalog can also be individually set to burn in on save or notSee Burn Mapping On Save preference.
Images rendered via RenderMan are, by default, in linear space, unless an exposure is applied to the output (which can be done in RfM via the Output Settings tab of the RenderMan controls).
If you do apply an exposure to your output, be sure to make the proper adjustment to the default image mapping for rendered images.
The OpenColorIO setup can be changed via your it.ini, though, as always, we strongly recommend making the changes in a site-specific surrogate ini file, referenced via RMS_SCRIPT_PATHS. "it" will also use the environment variable OCIO if it is set to find the OpenColorIO config file.
A special entry on the remap menu is the Shadow Map option, which is useful for viewing shadow map files. These files can have huge ranges that are well beyond zero to one, so the traditional way to display these has been to rescale the min and max values to zero and about 0.9, and then invert them with (1 - val).
