I hope you’ll do so as I have plenty of important rtf files that are very hard to discern now…
Update: Ok, I was able to change the color of plain background files as white, under the DTPO preferences - editing tab. However, I do not see the same option for the rich text files and they still have the black background. Any help here? Again, this is very important since I have many important rtf files that are hard to discern with dark background color.
