1) Offline Prestige
Unlock this as early as you can while still having a bit of extra prestige currency to unlock the important early upgrades. This is relevant for both the normal and the super prestige process.
That way, you can earn prestige currency offline without having to reset your progress and scale way quicker.
2) Printers
The guide does not mention printers at all, but I found them to be very useful after having access to a decent income of red prestige coins as well as the "Printer Printer" perk once you reach mythical leaves. With printers lasting through prestiges, they scale pretty great for this part of the game.
The Robot Leaf, one of the first two unique leaves you will likely unlock, boosts printer output by another 5000%. Don't sleep on printers.
3) Seeds
In order to unlock the unique leaves required for the 100%, you need a considerable amount of each of the leaves (up to 1^35 gold leaves). To get there, I used seeds and did not rely on blowing leaves any more. They start out by giving you 1% of your current leaves and that amount can be upgraded to 100%, so each seed doubles your leaf count. Once you reach them, try to keep as many leaves in your bank so you can scale exponentially. There is also a pet raccoon that doubles seed spawns and the rainbow leaf, the other early unique, increases the reward by another 50%.
