WordPress 2.7 has added some really cool admin UI and sadly broken tons of plugins that I was using to make the same UI possible in the past! So, the best approach is to upgrade to 2.7 and deactivate the Automatic Upgrade plugin. Another plugin that causes issues is the Lighter Menus. So, I have replaced it with the updated version of Ozh Admin Menu. Also, use the obsolete version of OneClick Install to install themes. Let me know if you use anything better to install themes.
I miss the Turbo link on top. Now, I have to hit the Tools link to update files for Google Gears. Turbo somehow gave a feeling that things were really getting faster. The subconscious was buying the power of the word Turbo. The word Tools doesn’t really feel fast. Clicking on the Turbo link at least made me feel I was making things speed up.
