Thank you for letting me know! I think you are on a good way to make Omniboard even better than Sacredboard, especially if you plan to continue with development.
But even if not, I guess there is a higher chance for you to get code contributions as you decided for a “mainstream” technology stack, which doesn’t require developers to know two different languages and a bit exotic Knockout.js framework like with Sacredboard. However, I was positively surprised last month with a nice contribution that allows users to view and download source files and artifacts via Sacredboard. Unfortunately, this was rather an exception.
I’ll notify Klaus Greff, who is the “main” author of Sacred, about Omniboard. I’m pretty sure it would be accepted on the main page of the Sacred GitHub repository if you create a pull request for README and include a few words about the tool and a nice screenshot.
Good luck with further development!
