BetterTwinklePrefs places a nice little Twinkle preferences link next to your usual Preferences link at the top of the page. It looks like this: [TW]. This script also suppresses those big Twinkle preferences notice boxes on JS and CSS pages.
To use this script: Copy the line below, then click here, paste the line, and hit the save button.
