For security and other reasons, I always want to see notes – for updates to any extension – before allowing updates.

Zero privacy. Collecting your data, sharing with unknown 3rd parties. Unacceptable.

Sync error with Dropbox for versions, and wiped out most of scripts time and time again. I cannot bear it anymore... : (

Stable, and allows pretty much all standard userscript functionality

Easy to use and efficient.
