Feature request.

So I have a grid of plots and want to examine one or more of them more closely. Possible options:

1. Clicking on the plot could pop up a modal window. Closing with Esc key or Spacebar would be nice.

2. Mouse-hovering would enlarge the plot while the mouse remains hovered. This limits the size of the enlarged window, or require positioning so that it doesn't interfere with the mouse pointer.
