There is a Gmail lab to turn off the unread counter, but the "Inbox" link still turns bold so you can still see that there's new emails! This user style forces it to be not bold.

Sets font size to 116% (about 15px) and line height to 1.4 in Google Reader. Only affects the content column, not the subscriptions list, but includes the post titles in list view.

Make completed TeuxDeux tasks turn grey immediately, so they are less noticable than those not completed.

Hides the "This account is managed by " for Google Apps users.
