How do we state and/or document that further work is needed after a Case? For example, some things I had in mind after finishing this case: *While adding the About comment for the Versionner tool I've found that the About should be modeled (at least to encapsulate the about text and the about window title, but maybe also for other information such as the purpose of the tool, the author, external link, further reading, etc).* *Should we generate a test for this About behaviour ?* *Should we move the About functionality up in the hierarchy and integrate it more with the classes used to make Tools?* *I added a method that answers the tool name (as opposed to the tool class name, usually used in the About title)* *and I found out there was another implementor on another Tool, but which I didn't understand the relationship with the Versionner.* *Is there something that could be done? Maybe make an abstract method?* *Is there a place where to put all these comments and questions/comments/ramblings?* *If there is, where?*
