Flowcharts and source structure tree views automatically generated from C source. EasyStructure hugely aids understanding source code from its analysis and resultant charts (can be browsed, printed or copied). Flowcharts can be customised. Tree view nodes are easily browsed and can be used to quickly find contained statements of various types (e.g. jump type, return type). Will also reformat/beautify based on the source structure.
