got this script to hide the bs trending topics on twitter (nonsense pop crap etc), does exactly that, love it :)
Not only does this script neatly hide the totally unnecessary and distracting junk that #NewTwitter introduced in the sidebar, but as a bonus it adds a button for doing the old type of retweets - copying the text of the tweet into the input field so you can edit it. Excellent.
This script runs flawless on 1024 x 600! It looks great and makes the whole interface simple!
