Twitter - RTL
Cleans up the head of twitter.com and improves readability of timelines with more line-height, font-size and the use of Helvetica. The first Tweet on a users Timeline is in the twitter-blue color, too.
For tylish plugin on Firefox. 1) Modify "update" button font as Vedana. 2) Modify "status text area" font as "Microsoft JhengHei". 3) Modify line height, letter spacing and font of tweets' content.
This userstyle removes elements of a user's Twitter page superfluous to reading their content.
Recently, Twitter's private-tweet lock image disappeared to me. It took a while to figure out what was wrong, but I tracked it down to the CSS 'inline-block' display property... which does not work in versions below Firefox 3. For those of you who are either unable or unwilling to update Firefox for whatever reasons (for me, it's an unwillingness to let go of an extension that isn't available for version 3), this may be of use. It restores the private-tweet lock icon. Of course, it has no effect on public tweets. Not very useful for anyone else, unfortunately; and I have no clue whether it works in versions other than Firefox 2. Credit goes to the following site (found through Google) for helping me figure out how to fix the issue: http://www.quirksmode.org/css/display.html#inlineblock

Like Twitter's new Retweet, but wish it was easier to spot the retweets? This style de-emphasizes their appearance, making them easier to recognize in your stream. Feedback welcome!
