Plugin or not plugin?


I need to extend a plugin functionality and the best way to do that would be to create a custom plugin.

The plugin I’m going to extend is Gravity Forms (they are going to release a beta version that will allows me, thanks to a new hook, to localize the reCaptcha in Italian).

Now, I was thinking that a plugin that simply provides a text box for each WordPress Hook and action, could be very useful.

I also think that it shouldn’t be so hard to write this plugin.

In fact, I was thinking to write one on my own, but I don’t want to reinvent the wheel, so here’s my question: anyone knows if something like that is already available (and maintained and supported)?
