Keep the Extra Missions tab focused on missions you still have to finish. This mod automatically hides a category when its Missions completed counter reaches the total, for example 3 / 3 or 5 / 5.
Categories with unfinished missions remain visible, including their completed mission cards according to your existing filters. The Other Missions category is also supported. Categories can return when the game refreshes them with new or reset missions.
The mod changes only which Extra Missions categories are displayed. Mission progress, rewards, and completion requirements remain controlled by the game. No configuration is required.
