It would be very useful to be able to observe zoom level changes on layers. I'm trying to keep a layer of points scaled by values in meters, so I need to recalculate the radii whenever the zoom level changes. I can work around this by observing the 'move' event on the map object and keeping track of the last zoom level, but that seems clunky. Am I missing a better way to do this? If not, how about adding this event?

I'd also like to be able to do this - I'm aggregating data into a heatmap geojson overlay, and knowing the level of zoom is useful for efficiency.

@RyanEwen

I am also observing the 'move' event and checking for the zoom level as this happens, but I am happy with that. It doesn't seem too clunky, but a specific 'zoom' event wouldn't hurt, either.

@hamroune

hi all, is there any workaround to check the zoom events?
