Usually if you are suggesting a plugin or behavior, it helps to give a comprehensive description and possibly an example list of the actions, conditions and expressions it might feature. It's impossible to tell what you really mean and precisely what you want it to do if you just give a one line or few lines saying that you want something. When a developer (if they have time) comes to develop it, they'll have to put a lot of thought in to how to design the plugin/behavior, precisely which actions, conditions and expressions to add, and so on. If you don't specify what you're after, someone may make one and it could be completely different to what you really wanted because you didn't say!
