Application Settings icon could be moved to the left while the other icons already there could also shift to the left (there is plenty of room). The rest of the icons on right sidebar are not critical or have a duplicate function like how Day Margin meter levels provide more precise information than the Notification that an account is getting close to liquidation. If the sidebar could be turned on or off then traders would have a choice: a more streamlined focused trading experience, or a more relaxed exploratory experience, with chat and news, etc.
