Control-clicking a view method in a URLconf will open views.py and bring you right to that method. Similarly, control-clicking template names in a view, and in other templates (like in the extends tag) will bring you to that template.
Not hidden, but when editing a CSS file, it shows the colors in the gutter for any styles that use color. I love that. Also for CSS: code insight offers optimizations of tags, as well as graying out unused tags.
When editing an HTML file, moving the mouse towards the top-right of the editor will display icons for several browsers...clicking those will open the current HTML in the respective browser. Not as useful if you're using Django templates, but another piece of IDE-candy nonetheless.
Auto-import is also probably one of my favorite features. It still needs a bit of work, though. This is just a preview release, so I'm sure it'll continuously get better.
Well done, JetBrains!
