Has your index finger ever been extremely sore after pressing down the W key for hours as you travel through Middle Earth? Well worry no more: Introducing the new Cruise Control feature! This would be a setting that could be toggled on or off in the options menu (although I don't know why you wouldn't want to make use of it). It would allow for the player to continue moving indefinetely even after they take their finger off the W key. They would still be able to change direction and jump, however. It could perhaps be activated by pressing a button while you are walking or sprinting, maybe the R key. It could be turned off by pressing that key again. On a similar subject, in the vanilla game, a feature called auto-jump was added, which could be turned on or off the the options and caused the player to jump if they ran into a block without pressing the spacebar. However, it does not exist in the LotR Mod, and I would love to see it added. Thanks for taking the time to read this suggestion!
(Although I know you shouldn't suggest two things in one suggestion, cruise control and auto jump are such similar subjects that I would count them together as one suggestion.)
