Gmail will soon let you turn off Conversation View. But that's not what this is about. This is about inconsistent capitalization. It drives me nuts. "Conversation View" (title case) is not capitalized consistently with the other headings in Settings, like "Maximum page size" and "Keyboard shortcuts" (sentence case). But that's the name of the feature, you say. Fine. Within the setting itself it's not consistent! If you pay attention to the image in the blog entry, you can see that the heading is "Conversation View" but the radio button labels say "Conversation view."
Yes, I filed a bug. No, I haven't heard anything about it.
Details and polish matter, people. Ask Apple.
