Did you notice the recently update on Google Docs Spreadsheet? I am referring to the insert comment feature of the spreadsheet. The comment looks like a thread now. It sends a notification to the involved parties and it displays the avatar of the one who inserted the comment and when the comment is inserted. There is also a Resolve button on the comment area which could flag the comment if already resolved.
The call-out button on the left of the sheet title tab displays the total number of comments posted on the particular sheet. If the button is clicked, all the comments would popup. Aren’t these new comment features are so cool?
As a moderate user of Google Spreadsheet, I value this feature because I don’t have to write my name when I post a comment and I can immediately identify the other commenters.
