Not a bad plugin, but certainly has potential for use when people are teaching others to jump.
A few things about the plugin when it was installed...
- The plugin started in debug mode, resulting in the chat spam of "{olive} <playername> rocket_jump" etc
- The tracers were enabled for everyone, resulting in a mass of green lines being displayed for some particular jumps (those with a high amount of users)
However there are some things in which could be implemented to greatly improve the plugin...
- Set the plugin so the tracers aren't enabled by default
- Make the tracer enabled through a command such as !trace <playername> 0/1. So you can either toggle it on or off for a specific target
- With the above point, you would need to make the tracer viewable only from the player who enabled it, otherwise it would again cause a mass of green lines
Hope this helps
