Please consider the possibility of contextual display a document relative to the position of the cursor.

The mainfame editor, ISPF, provides the capability to display a document based upon the position of the cursor: Relative to the line on which the cursor appears, the line of the document is positioned to the top, middle, or bottom of the screen. EMACS and Vim also enable this functionality via "Line to Top", "Line to Middle", etc. 

Please consider the possibility to include this functionality to facilitate program development and text editing by displaying portions of the document relative to position of the cursor.
