UX Annoyance: When clicking on an exception, there's no visual indication that it's been clicked on. I found that Shift+Tabbing brings you back to the editor pane (other than using the mouse).
A couple more things that could just be me being stupid. When I try to eval using Ctrl+Shift+Enter, nothing happens. Instead, I have to eval each line one-by-one. I tried creating a new key binding, but couldn't figure out how to delimit my keys to allow modifiers. I also can't figure out how to pop up documentation or data flow as demo'd in the original light table (this is my first time using any version of light table). I tried `(doc <foo>)`, but it just evaluates to `nil`.
Anyways, hope these comments might be useful in terms of my user experience as a first time user.
