Inside the game garage there is a bell icon in the lower right corner where you can check your notifications. The game very frequently adds badge notification pop-up numbers to that bell, which is very distracting. Normally the only way to get rid of that is to click on the bell icon but what you usually find is that almost all notifications are useless.
This mod fixes the problem by removing the numbered notification badges from the bell. You can still check your notifications as normal when you want to.
