There are a few things I would like to see changed.
1. Since Ui7 is going with the design of bottom up instead of top down for better one handed operability, I would like to see the settings cog wheel on the bottom of the shade and quick panel.
2. The battery pill needs to be longer and bolder. Samsung customers tend to skew older. For some of us of a certain age, we CAN'T read the % number!
