There are more hidden here and there in articles. I wish there was a single directory page that showed all icons and linked to pages with more information specifically about that icon.
Thanks for the link to the "Rolled Back Feature" icon! I looked for that but could not find it. I agree with you that it would be really nice if all of the Alibre icons were included in one location in the online help.
... be nicer if the status of the item was shown in a tooltip when you hovered over it in the design explorer! ... no searching for icon definitions at all. UI 101, make the UI intuitive and easy for the user.
