Talking of weight and spacing it would be great to be able to adjust these independently.
A quick one on candles - a way to bold the wicks without bolding body outlines or, even having body outlines would be great.
For a discretionary trader (for example someone trading price action around support resistance) visulisation and emphasis is pretty important and these tweaks would be very valuable. Ninjatrader on the whole looks great but I still find myself using other charting because of the control they give me in these areas.
