Charting features I'd like (off the top of my head)...
- Click bars/candlesticks/days on chart, SS draws best fit support/resistance line through them
- Freehand drawing to highlight chart formations
- Alternately, draggable curves (ie fix end points then can drag mid-point to change arc, to highlight curves
- Wider range of line styles - I'd like a wide/faint band to highlight an Area of interest
- Ability to add circles/ellipses to highlight formations
- Force line horizontal (ie drawn a not-quite-horizontal line, and want to make it horizontal)
- Lines that stay drawn through the correct points when the timescale is drastically changed (ie going from a long timescale, highlighting a small section of that will have the drawn line going through the wrong points (miles out, in fact) - I have reported this one before)
