Nah, it’s definitely available in 10 - used to use it a lot on my dual monitor setup at work and that’s still not upgraded to 11. Fell out of the habit of dual monitoring during the pandemic so it hasn’t really been necessary since…

Didn’t know about this Powertoys feature, neat - think Windows actually has a built-in option you can toggle where if you hold down shift (or possibly ctrl? Haven’t had cause to use it for ages) it’ll highlight the cursor with a bright circle.

I recommend a DNS-based ad blocker like NextDNS. Works on everything, everywhere!
