Within Teamwork Desk you can like notes left by your colleagues on tickets.
Liking a note can help to cut to down on unnecessary replies confirming that you have seen their notes and help to keep ticket threads shorter.
To like a note, open the ticket and locate the note. Hover over it with your mouse and the like option (thumbs up) will appear to the bottom right of the note.
Click the thumb icon to like. You will then see the thumb turn green along with You like this to the bottom left of the note.
You can also remove your like by clicking the blue unlike option next to You like this.
