Is it possible to view the current X/Y location of the cursor on the canvas?

For example, if the cursor is in the upper left portion of the visible canvas, it shows as [0,0 if using upside-down cartesian] (or [0, height-1])?

If so, how do you activate the feature?

If not, could this feature be added in the future?

I think this would be a good feature for pixel artists and tiling.

No, that's not yet possible. Last time we implemented it, it caused a huge performance slowdown, and we haven't tried ever since.
