Editable DOM or Drawings Show up

To the program mod gods:

I  think it would be a good idea to allow the column where chart indicators show up on the DOM to be editable. Maybe allow you to type in just a few characters in different colors. Barring that, it would be nice to have chart drawings in the chart indicator column of the DOM. Maybe by the color drawn at the level, like a horizontal red line drawn at the value 2868 would have the chart indicator column of the DOM red at 2868. And a handdrawn diagonal line would just light up more of the DOM since it would contain multiple values.  

And adding a time expiration or time to look (only look at drawings from the last week type thing) at drawings component would definitely help keep things looking clean on a day to day basis. 

Thanks for even looking...
