Wekan https://wekan.github.io has:
- Dark Theme at => Board Settings => Color => Dark. Although, only for per board, not as Global theme yet.
- Markdown and GitHub emojis https://github.com/wekan/wekan/wiki/Emoji
About comparisons:
- Yes, comparisons are very time consuming to make. Most comparisons at Internet are out of date, usually new features are added to software all the time. I also have not found up-to-date comparisons site. Comparisons pages can also get very long, some kind of summary would be nice, if possible. I should sometime try to update this out-of-date comparisons page https://github.com/wekan/wekan/wiki/Wekan-vs-Trello-vs-Resty... , after creating that there has been many changes.
- For example, Wekan has some same features that Trello also has. Wekan has some features Trello does not have, like Open Source, self-hosting, Swimlanes, etc. Trello has some features Wekan does not have, like burndown charts.
