Do you find the original auto-jump hard to use? The main thing this mod does is that it makes your ascent smoother, just like the original horse.
StepUp allows you to walk up one block height without jumping.
It works on both Singleplayer and Multiplayer servers. Press "H" to switch between modes in-game.
You can change the key bindings in the settings.
