The launcher ui in it's current state is very nice.
But all the round objects like buttons and drop down fields are not coerent and feel very far away than the rest of the style of the launcher.
So current possible improvements can be:
-Make buttons edgy eg. windows 10 ui.
If the previous improvement is made. The background colors of the buttons can be set to the same color of the icon they are holding and the icon color can be set to white or grey.
-Change overhaul launcher ui background color saturation. As i feel like the background color is too much going for the grey.(proably bacause of the ui tabs).
Probably good adjective for describing the suggested colors is : bright colors?
