There are two different approaches to navigating in playground - either using the keyboard arrow keys, or clicking on something and your avatar will automatically walk towards it. This latter approach I find REALLY irritating when building playgrounds, as I'll click on an item (to select it, in order to then move / resize / whatever) and my avatar will walk to it instead. Particularly problematic if this causes my avatar to accidentally fall in the water etc. Similarly, some of my students keep using the "click to move" approach and careering chaotically all around the playground (even though I know they are also using computers, so could use the keyboard no problem, and indeed have done in the past). Yes, it's hilarious, but can result in very distracting giggling / wastes time we really could be spending on the lesson itself. A couple of my students will happily spend 10+ minutes non-stop messing around like this, despite multiple reminders to focus, and it's becoming quite problematic. Can we please have a way to disable different navigation methods, both for the teacher and the student?
