Sort items by when they were started in chat layout

Sorting conversations and tickets in the order they started can now be done from chat layout with two new sort options – Started first, and Started last.

Previously only available in table layout, these sorting options will show a list of items that won't change position. That can make it easier for fast moving teams to keep track of which conversations they want to reply to first e.g. you can more easily take a 'first come first serve' approach.
