When used in "center" mode, the text on DS can become illegible if the color of the icon behind it becomes too light, it should be able to automatically change the way MS objects do. See picture below for example:
Thanks Tyler. I will start a discussion about this. It is a little different to how colors work in Magic Sheets, because these are derived from a single background color. In this case we would need to take either a predominant or average color of the image which I can foresee having a performance impact.
This has now been written up for consideration.
