I think more attention and time should be invested into planning of jumbo and *2john tasks because they're most important there. So in tough words: the core of your roadmap is not thought well. And I'd put these tasks earlier. BTW Version 1.5 1. Add the –fork option to the UI so that we can use multi core -fork is not the only option for multi threading (openmp, mpi).
