Do you find it hard to keep track of all the code related to your software modification task? Do you wish you could keep a permanent record of the subset of a software system associated to different concerns (requirements, design decisions, tasks, bugs, etc.)? ConcernMapper does exactly this.
ConcernMapper is a plug-in for Eclipse that allows you to organize fields and methods into arbitrary modules called concerns. In brief, ConcernMapper allows you to reorganize the modularity of a software system in a way that suits your needs, without altering its "official" structure or behavior. It also allows you to keep a permanent record of the code associated with various concerns.
