BranchView can be run standalone or can be integrated into Eclipse IDE. This work is done by BranchView plugin for Eclipse. Within Eclipse IDE you do not need any external diff tool, because BranchView is seamlessly integrated into Eclipse and use internal Compare tool.
BranchView can use P4Eclipse plugin for Eclipse. This tool is also free and is a fully integrated P4 Java client for Eclipse users. With P4Eclipse installed, BranchView don't need extra configuration parameters, except P4 command line executable path (if this path isn't set on OS).
New in version 1.0.1
Reflecting fixes in new BranchView version.
Tested on Eclipse 2.1, 2.1.2, 3.0. May be still working with 2.0.2 ;)
