Every section will include one line containing its status (Open, Decided, Work in progress, Finished, Tested and Closed).
Of course, fell free to use the [Bugs System] to follow the daily evolution of each one of these problems by adding one link inside each section pointing to the proper bug.
Prior to change the status from Decided to Work in progress the corresponding page of the roadmap must be modified, including all the actions/steps needed to solve the problem. Obviously, at the end, the expected status for each section is Closed.
