Google have fixed my number 3 gmail bug.
If only they could fix the other two major flaws of gmail:
1. The gmail search sucks (cf normal google web search)
2. Gmail doesn’t understand attachments from Mac Mail.App (the suffixes are missing)
Now if you’re reading a conversation that had unread messages when you opened it and you mark it unread, Gmail will only mark those messages that were unread when you opened the conversation in the first place. It’s a small change, but it’s the little things that can make a UI feel right or wrong, and we hope this makes Gmail a little bit more right.
