I can recommend trying out Empear’s CodeScene tool - it takes source control analysis to a whole new level and highlights many issues.

For example it will help you figure out relationships like when I add another widget here I should remember to add new switch/case clauses there and there and there.

Another nice approach is using static analysis tools to look at metrics like cyclomatic complexity, coupling and the dependency structure matrix to find the most important and troublesome parts of the code base.
