I've had instances where I see the title to the thread on the right hand side, but it only shows the first few words of the title. When Iclick on it, I have to read the full title to see if there is a warning somewhere in it. If you do it at the beginning, then it would be noticed even if it's on the right hand side in the list with only the first few words visible before even clicking on it.
Just a suggestion.
Another suggestion is either changing the warning to include the page or editing it to also include the page that the warning is on. Telling me it's #691 in a 60 page thread doesn't help much. But telling me it's on page 45 would get me there in a hurry.
Just another suggestion.
