Crosshair Tracking

What I need is a plugin that can track my crosshair..
For example, I want to be able to have particles follow where ever my crosshair is pointing.
Perhaps the command would go something like:
/particle flame CrosshairX CrosshairY CrosshairZ 0.5 0.5 0.5 0.01 10
Or
/execute <playerName> Crosshair ~0 ~0 ~0 particle flame ~ ~ ~ 0.5 0.5 0.5 0.01 10

Vanilla command:
/particle <name> <x> <y> <z> <xd> <yd> <zd> <speed> [count] [mode]

Or, with a right click detection machine set up with command blocks, the tp command would go something like:
/tp <Player> CrosshairX CrosshairY CrosshairZ
and it'd work sorta like an ender pearl.

But mostly, I just want the particle part to work.

 

Is there one certain function that this plugin should have? The request seems to be a little vague. Did you just collect some random ideas that came to your mind or is there an exact purpose behind this plugin idea?

 

Well the main reason I want this plugin to exist is to create particles that follow your crosshair (or cursor), so it'd look as if you're controlling that particle like a super power or something similar. I imagine that this plugin would be useful for more than just that tho, for example, activating any sort of command in the direction your crosshair is pointing, an example of that might go something like: /execute @e[crosshair:front,r=3] ~ ~ ~ summon lightningBolt ~ ~ ~
which would summon a lightning bolt at the coordinates of all entities in front of where your crosshair is pointing in a radius of 3 blocks.
