The author has marked this style as obsoleted by Gmail Dark-Grey No-Nonsense.
Has some bugs in it too.
Collection of my favorite Gmail patches for https://gmail.google.com/
- Uses a changed version of http://userstyles.org/styles/172
- Uses a warm light-grey background, instead of white.
- Uses monospaced font for non-HTML mail.
- Adapted sizes and positions of several parts for more economic screen-usage.
- Better highlights open mail-folder.
- Hovers over mail with colors
- Removes some ads.
Still working on this one (there's an ugly white stripe left of open mails).
Thanks to arteekay (rtk) and Jhon for some base.
