As a company we have many people that look at our Smart Sheet so we can all stay up to date on our latest projects. That being said we rely heavily on the comment section to keep everyone on the same page.
It would be nice if there was a way to "like" a comment, or once someone views the comment you can click it and it will show a "seen by" roster.
If everyone was to comment that they had read a message the comment section would get very long, unorganized, and the important information may go missing.
