String Literals just got a little smarter!
You can now convert a normal strings to multiline (with triple quotes) string. Notice how the special characters are escaped. (SCL-2991)
And back again:
Similarly, when you paste some text into a normal string (for example: C:\path\file.txt), the appropriate escaping is added. (SCL-3144)
Finally, you can now autocomplete, navigate, and rename-refactor references to classpath resources in string literals. (SCL-3138)
These features require a nightly build of the plugin, with the latest EAP build of IDEA 10.5.
