Window ==> New Editor

…will bring up a new editor for the current file. You can position this in Eclipse wherever you like to see multiple portions of the same file.

Eclipse Marketplace has a variety of eclipse tools and plugins but the following is a list of very useful Eclipse plugins that I must have.

• Perforce Plugin is a must have for developers using Perforce as their revision control system. Once setup, it provides seamless integration with P4.
• SQL Explorer Plugin is a nifty little SQL client that allows you to query and browse any JDBC compliant databases. It supports Oracle, DB2 and MySQL and could be extended to include support for other databases.
• JadClipse Plugin is a must have for seamless integration with JAD (Java Decompiler)
• FindBugs plugin is used to perform static analysis to look for bugs in Java code.
• Regex Util (Tester) plugin is used to test Regular Expressions.

The following is a list of plugins you might need depending on the nature of your work etc.

• BIRT is an Eclipse Based Reporting Framework.
• Tomcat allows integration with Tomcat.
• ADT Android Development Tools is an excellent plugin required for Android Development.
• Ivy if your application uses Ivy for modular dependency.
