Move Mastery challenges to a new Career tab and change the UI/UX to be visually appealing and easy to see progress for weapon collection at once.

When I click on Challenges box in Play tab, the weapon Mastery button is barely visible in bottom left corner and cannot be accessed using controller in Challenges. I have to use a mouse to click it which defeats the point of playing with controller.

It takes a long time to scroll down through all the weapons after all the weekly challenges is shown in a long list format.
