View White Space

Quick question: How many of you use the 'View White Space' feature in Visual Studio?

The 'View White Space' feature can be activated through the Edit -> Advanced -> View White Space menu option, or using the Ctrl+R, Ctrl+W key combination (at least on my keyboard layout).

Personally, I only use this very rarely, though I admit it is occasionally useful, for example when working with positional flat files. I do wonder, is there any of you that uses it full time while coding?
