I've definitely wanted to make plugins for Sublime Text that show a live preview in another pane. Unfortunately there's no way to create another pane of anything but text, so the current solution is opening new windows (for things like Markdown Preview, or Graphviz).

When I get some free time, I would like to see if it's easy to do in Light Table. Since it's open source, anything should be possible with a bit of work.
