Small request: Settings page could be a bit easier to use

Hey there, from my early usage of this plug-in it seems brilliantly simple and is totally solving an issue I had with getting data from a specific source into my site!

The one request I have is could you make the settings page a bit easier to work with? A text field that only allows 25 characters to be visible at a time is a bit of a challenge to work with particularly as it’s critical to making the plug in work.
