Currently, IQ treats the [ # ] column of the current [Item] as the INDICATOR for the currently focused Grid Row by changing its Fill color. Unfortunately, that column can scroll off the screen so the user not only loses the visual indicator down the left-hand side of the grid but also loses the ability to select an entire grid row with the mouse. Most grids have the option of showing a fixed current row indicator ">".

Would still require manually adjusting this setting for each and every Grid to achieve "expected" operation. A Global Option would be better; # of Locked Columns = 1 by default. The [#] is already "special" in that it can't be moved, removed or have other Columns placed before it; it can be hidden though which may cause some confusion.
