A very nice feature enhancement would allow users to readjust columns in the "grid" to optimize the display. If you have many columns, one for each field name, some columns often end up too narrow and some way too wide. Even a dumb feature that allows the user to set all columns to some default width by clicking a "resize" button, sat something like 12 characters in width, would at least expand the too-narrow columns and shrink the ones that are too wide. This simple step would then make it easier to adjust column widths to their proper size for viewing.
Or you could do like iTunes' media player and adjust each column to the size of the data in the columns.
Another scheme would allow users to right click in a column heading and choose "Optimize width."
