Rare Quest Tracking Tool
With the release of Chapter 2 Season 5 (aka Season 15), Fortnite removed Punch Cards and merged them into the challenges, relabling them as "Quests". This new Quest system has different rarities of quests; more-or-less classfying what each quest is by rarity. The blue (rare) quests are what used to be Punch Cards. However, the rare quests don't appear in your list until you've got about 80% of the progress done, and then disappear once you've finished that step (even though they have 5 or 6 steps); making it quite frusterating to track. As a completionist, that wasn't going to work for me.
Enter the "Rare Quest Tracker". This tool takes my list of rare quests and divides it up into the individual challenges. It also allows you to click each step you've finished, marking it green so you can quickly know just how far you are.
Running multiple Fortnite accounts on your computer is impossible using the Epic Games Launcher. But not with my special Fortnite Launcher. This tool uses command-line parameters to launch the game using locally stored credentials, saving you the hassle of having to swap between accounts. Additionally, since this tool doesn't make use of the Epic Games Launcher, you don't have to worry about closing it when you exit the game. Plus, it uses way less resources than the Epic Games Launcher, so I call that a win in itself.
