Neither Chrome or Windows version recognized my Galaxy S3. Followed all the steps, installed universal ADB drivers, enable debugging and PTP

Solid extension. Unlike most start screen replacements, it doesn't seem to cause any sluggishness. Can't seem to get the App button in the lower corner to take me to the apps page, but that's a minor complaint.

Neat start screen extension, I especially like the reddit section.

Nice idea, execution leaves some to be desired. I'd like to be able to set my location manually, or at least save it so it doesn't have to load every time. I'd like to be able to remove the pointless search bar, as the omnibar already serves that purpose. I'd love to be able to choose what subreddit/s are in the reddit section, and I'd love to be able to change the weather to display in Celcius.
