I'm maintainer of Wekan https://wekan.github.io
Wekan is Open Source kanban board software https://en.wikipedia.org/wiki/Kanban_(development)
Wekan is available for these platforms https://github.com/wekan/wekan/wiki/Platforms
Wekan has MIT license.
Here is summary of Wekan history: https://blog.wekan.team/2017/12/2-years-of-wekan-what-we-archieved/index.html
Wekan does not have Themes feature yet https://github.com/wekan/wekan/issues/781 , so I can not ask for Star Trek Control Desk interface theme for Wekan yet. There is often new features that change Wekan interface, so making other theme currently is a lot of work. Because themes like Trello are copyrighted, I can't include them with Wekan. What is status with Star Trel Control Desk interface? Is there themes for it somewhere with license that is same or similar like MIT Open Source that Wekan has?
Mainly I'm asking this, because there is growing interest to space travel like at http://www.spacex.com . I don't yet have any paying customers requesting features related to this to be able for pay for translations. With upcoming Friend platform listed at platforms page https://github.com/wekan/wekan/wiki/Platforms and FLOSS Weekly interview https://twit.tv/shows/floss-weekly/episodes/450 , Wekan would be available for example at Android and iOS mobile platforms, so I'm thinking if Wekan could be used in some order management system like https://github.com/wekan/wekan/issues/1473 for example for shops etc on earth or between planets. Workflows can be implemented with for example Node.js like with Gogs integration https://github.com/wekan/wekan-gogs or then some workflow tool like Huginn or Flogo https://github.com/wekan/wekan/issues/1160
