We recently launched a new major version of JCreator. If you haven't yet, please take a look at new features.
They include handy tools to increase your performance such as:
On the fly import suggestions, no need anymore to scroll to the header of the document to insert an import statement.
As you see, JCreator will also highlight incorrections as red text.
Another cool feature is to rename classes, variables and methods accross all your projects files.
For the full list please refer to http://www.jcreator.com/features.htm
Feel free to contact me if you have any questions.
