First of all, on the Minecraft Feedback website on mobile, I can't read what I'm typing. It's just white characters on a white text box. I'm in Dark mode. Second, when I'm on mobile and using a controller, I want to have an option to where I can turn on Sprint with the press of a button, but don't have to hold it down to continue sprinting. This is achieved on mobile by pressing the Sprint button, and the Sprint being activated for as long as you are running in that direction without stopping. I want something like this to be applied when using a controller.
