Thank you for your feedback! You can easily implement your own JustCode extension. I did a quick example that works pretty much like Just Clean All, but for open files. Feel free to experiment and let us know if you need further assistance. Just build and put it in [JustCode Install Folder]\Libraries\UserExtensions
In the example the command is placed in the solution explorer context menu. You can make it like a refactoring command (in the visual aid) and use SolutionModel.AllUserFiles to get all solution files.
