Seems to me the option to add text should output the additional text after the Custom Field value in most use cases, rather than before. At any rate it would probably be best to have the option of both before and after.
Here's my use case. I routinely use Custom Field Widget to display customer reviews in the sidebar (works great, I LOVE this plugin btw). In all instances of these testimonials I have a link at the end which goes to a testimonials page and always reads "Read more testimonials." This of course makes more sense at the bottom of the whole thing, but I want to use the Widget Text option for it, so I only have to write the link one time (as opposed to writing it in the Custom Field on each page).
What are the odds of adding another Widget Text option for output after the Custom Field output.
