ParCool!
By alRex_U
ParCool! expands Minecraft movement with a broad set of parkour actions and dedicated animations. Run along walls, jump away from them, vault over obstacles, slide, crawl, or cling to a cliff edge as you move through the world. The mod also includes dodges, dives, faster running, flips, hanging, and breakfall moves, giving you more ways to approach routes that would normally rely on walking and jumping. Each action has its own animation, helping movement sequences feel more fluid. A wide range of configuration options lets you adjust the experience, with settings intended for individual players, modpack creators, and server hosts. Open the in-game configuration menu with Alt+P to explore the available options. A separate guidebook explains the actions and controls; installing the optional Patchouli mod makes that guide available inside Minecraft as well.

Freelook
By Celibistrial
Freelook is a Minecraft mod that lets you look around freely without changing your movement or character direction. Freelook brings a popular custom client feature directly into your standard game setup. By holding down a custom keybind, you can pan the camera to scan your surroundings while your character model continues traveling seamlessly in its original direction. The camera angle instantly snaps back to your standard view the moment you release the key, making it ideal for checking your blind spots in third-person view during long journeys or flight.
