This simple datapack give you a book with lots of different commands survival Minecraft. The flight has three different settings that allow you to have a lot of control over flight in survival mode. Just click on whatever setting you want to activate.

  Clear Flight stops you from flying. You will immediately fall to the ground, but you'll have immunity from fall damage for a few seconds. Flight makes you fly up. Hover makes you stay in one spot vertical, but you can still move horizontally. Slowfall makes you slowly fall downward.

This should work in multiplayer as long as you have access to commands, but keep in mind that opening a book in multiplayer doesn't pause the game like it does in singleplayer

  I am open to adding more handy utilities if they are feasible, so let me know what you think
