Display last message date in the folder-view

It would be great to display the last message date in the folder view.

I know the list is sorted by Date, but as i use folders, i often do not know what is the latest chat on a topic, as i mostly leave the autogenerated titles.

It would be helpful to see how "old" a chat is, so i can see what i used recently.

Would not need to be exact (time of a day) but rather how many days, months, years ago it was.
