I don't know how many other people find this rather annoying but when you misspelled in the 'Find Type' dialog in Jade 6 it still found what you wanted most of the time. In Jade 7 this has changed.
For example if you go to the RootSchema class browser and push F4, then type "FileNa" - In Jade 7 this will not be found. But in Jade 6 it will come up with FileNode. I liked the way Jade 6 worked where it was a bit more lenient
