For example, Imagine I'm viewing path [:a :d :e :g], and let's say :d is derefable. Am I able to click refresh on :d on that path, and have the data below :d get refreshed?

Some design issues:

• should values be refreshed on push/pop?
• what happens if the current path no longer exists after refreshing?
• what happens if the current path throws an exception on refresh?
• should there be a way to selectively refresh some atoms and not others? (I'm leaning towards no, but I'm open to being convinced otherwise)

How I imagined it would work is roughly like this:

So if you click on the deref, everything from there on out would be refreshed.

I'll think about those questions and see if I can come up with any ideas.
