Gmail just added something I've wanted for a long time - the ability to forward all messages in a conversation at once. Hooray! Perhaps due to my over-exhuberance (GOD I love GMail!), I've made that "far right menu option" stand out in bold red. I believe the div[class="ar'} would apply to all items in that list, but I just wanted "Forward All" to stand out. You can obviously change the font size/color (MOST of you will! Ha ha!) below; this is just my preference.
I used this for myself.
I still like the google's original font and color. I just need the hovering effecto. So I remove the font and color part of the solido's script.
Customize the Gmail navigation menu. Folders, Compose and Contacts I use this with Google 8pt v2.2 by PhiloHippus
Google Search Box becomes wider and with font colour red. It is optimized for 1280 sized screens.
Removes text ads, expands message area, removes page footer

for myself, only change the default font color.
Those of you who have installed Office 2007 might have notived the new font: Calibri. Personally I liked the font so much that I adobted the Tahoma (unified font) style and made a "Calibri-version". It is set to 10px and I hope this will work ok on the various Google pages and for all your different resolutions. Since the font-size is unified some headers that originally were sized up will with this style be same size as normal text.
Changes Google pages to use this font face. This is for us Linux users. I use Ubuntu, but I am sure this font comes available with other distros. If you don't like this font, simply scroll near the bottom of the code and change it to the font that you want. Based on "Google Tahoma (unified font style) v0.2" found at http://userstyles.org/style/show/178 UPDATES May 30, 2007: Commented out the code that widens margins in Gmail (toward bottom). I like using Gmail Air Skin and it was messing with that one big time.
