Real time market quotes
The change where the market quotes at the top of the main page change from red to green depending on whether they are trending up or down is HORRIFICALLY TERRIBLE. On the mobile app, especially in red, it is extremely difficult to distinguish between the + and the - signs.
I would suggest that all positive quotes remain green at all times and all negative quotes remain red at all times and, if you want to provide a secondary indicator for the trend then by all means. I am certain that I am not the only one experiencing this difficulty.
