How to disable snow effects?

[Nwhis]

I'm trying to use the online editor to make a new theme, but the snow effects are absolutely destroying my cpu, causing it to run at 100% constantly. I can barely use the site like this.

There used to be an option to turn it off, but I can't find it anywhere...
Was it removed or something or was it moved somewhere else? Because I really need to turn it off.

There's now a button at the homepage, in the bottom right corner of the snowfall panel.

It's a little glitchy, but it works, thanks for adding it :P

Any reason for removing it in the first place?
(also noticing there's no background-changer, is that just a seasonal thing?)

There was no button to disable the snowfall before. Yea, this is a seasonal thing.
