I did test this script against all the other snow ones, this is the leanest. We are also running significantly leaner than Amazon. I am going to do some more work to let folks decide if they want it on desktop, mobile, both or none.
I for one am not a fan of such scripts but they can be fun to play with. On the 8 year old box they suck.
Thats why its an option, not mandatory. If you want it, you can have it. If you don't, thats fine too.
A little sluggish on my almost 4 year old I5 laptop. I've had it running since you made it available, but turned it off today. Laptop is smoother now. Running latest Firefox on latest Mint.
