Documentation
I have gone through so many different options for calendar apps and so far the best one that I have found is closed-source and has been replaced with an updated version that requires a subscription model.
I really think this app has potential to compete with being the best calendar app for linux and I was wondering if there is any documentation or wikis to describe how it was designed, what the development roadmap is (if any) and any coding and/or noncoding things (websites, logos, .etc) that people can do to get started with learning how this project is run/designed and helping further your goals
There is no documentation or wiki to describe its design, and the development roadmap is just the github issue tracker. Sorry for the underwhelming answer, I just don't have too much time to commit to this project. But, contributions are very welcome, both coding and non-coding things. Just open issues for everything you think the project needs, and then they can be discussed and prioritized.
