Is there anybody with me to want the icon(custom app icon) instead of the accent colour 1?1 tile in the app list and start screen( can give an option for start screen)????
I am not sure I understand the question correctly though but are you asking if there are apps which allow you to create custom tiles on the start screen? If yes there are plenty of tile generators in the app store.
Personally, when I long press a tile that uses solid color, I would like to see a "set color" submenu with two/three options - 1. Use accent color. 2. Pick a color using color mixer and 3. Use default color (optional. for apps that use their own solid colors).
