Okay, so the edit post window has the "ins" and "del" buttons that puts an <ins> and <del> tag into a blog post, to indicate when you've inserted or deleted text since the original post. This is indicated to the blog reader as text with underline or strikethrough. Fine so far.
The timestamp/ datetime is also put in as an attribute of the <ins> or <del> tag. It sure would be a lot more useful if the datetime was displayed, perhaps as a tooltip, when the mouse cursor is scrolled over the <ins> or <del> tagged text.
As it is now, how else can a blog reader see the datetime except to view source?
