The current way you can't even see at what Y any value is unless you count it yourself
300% agree, I'm working on a few array and the biggest is 150x100x10 array. It's hard to determine (close to impossible) whether my project is working as it should, there's no visual way to tell me if i missed an array index offset by 1 or simply the intended value had change or not.
Maybe Ashley could have a look at this to offer a better readability.
+1 to this. I want to emphasis that the readability of the debugger does a lot of impact in doing projects efficiently. I rather use the automated debugger (a better readability than the current) rather than wasting a lot of time creating my own textbox/spritefont/etc debugger for the arrays.
Time should be spent more on working on events/codes/mechanics for the game, not debugger.
