Add metadata to nodes #17
Description
It would be great to be able to see which model generated a given node of text and and under which parameters. Maybe this could show in the minimap minibuffer? Though right now we show the beginning of the text. Could be a toggle or maybe once we've solidified the menus it could be shown by holding SELECT or something. Could also use different icons for different models, maybe? Instead of just circles we could have a shape for each type of model?
