Not very well known plug-ins you want to share with everyone

What are some plug-ins that you know of that are useful that you feel like aren't very talked about or used in the community?

Some of my examples are "No use player", really great for farming runs when you try to use a seed on a patch and a player is under you. "NPC idle timer" can be used to put timers on fishing spots to let you know when it will disappear soon. "Delete unsent message" clears your chat box so you don't have to delete the "111111" in your chat box before typing a message.
