The title says it all, it would be great if drops could be an execution command. An improvement to this feature could be to let the usage of some special variables on commands like @p (The player that caused the drop), @t (The tool that caused the drop), etc, etc.

Already there :) See the "command" parameter here: http://dev.bukkit.org/server-mods/otherdrops/pages/parameters/#w-actions

Example:

  ZOMBIE:
    - message: "running a command!"
      command: "/say %p used a %t on a %v to get a %d."

Closing the issue but feel free to comment :)
