1. Would be nice to see a plugin which used hooks such as OnPlayerInput in order to run server.effect then the prefab but set up in a nice easy way and adjustable per item. For example pressing R whilst using the candy cane produced the lick effect.
     
  2. The list of usable (sound)-effects is nearly short and limited, cause usable effects are a combined in visual and audial effects.
    So such a plugin, if someone starts to make such a thing, would also need to provide a manual-slected list of usable "sounds".
     
  3. Yeah, for example would be cool to add the jab fx and such to melee hits
