RFE Virtual Spaces/Whitespace
Visual Studio has an amazing feature that a number of editors including Sublime have begun to pickup and that I am a personal fan of. Specifically when you click in an area where there is no whitespace or click on a tab indented area, the input cursor will be all the way at the beginning of the line or the end of the tab in normal text editors. With virtual spaces when you click in these areas the editor will still move your cursor there even if there is no actual whitespace there. This would preferably be an optional feature in RTFX.

While it may seem as though this could be bad for code editor's because of the ambiguity about what is actual whitespace for revision purposes, I think that is solved by #174 with visual symbols for tabs and whitespace if that is possible.
