I like it for the ability to see the map or my inventory while I'm moving, but it's very annoying to use in its current state.
When I want it to activate it doesn't (happens a lot when riding horses), when I dont want it to activate it does (e.g. sneak forward for a few seconds and it'll put you in a full on auto sprint; great way to die at dome).
IMO it should be bound to the sprint button so it can be enabled/disabled at will
