triangle tab

In the older versions of Limewire there was a triangle tab in front of an item that could be clicked to show a drop down list of multiple files. This feature was the primary way I could determine if a file was real or a virus. For example, if it expanded the name of the file X.exe 25K under it would be the same file multiple times. If you than browsed the host the same file would expand to include maybe one hundred files under it all different titles but the same file size--this was the way to see it was a virus. Would you please restore that function?

Thank you
