Thats a one great site, thanks. However the roadmap there is the roadmap of Xeline, not the one of XEL.

Saying that... roadmap is a nice thing to have, but it adds little value for development. It is useful for general public, so they have some vague idea on what are the project's goals and timeline. However serious crypto projects like this one explore an uncharted territory, so the goals and especially the timelines are constantly moving/shifting... Hence having a roadmap often creates more harm than good, because people wrongly consider it as a list of 'promises' and start complaining when those 'promises' are not fulfilled.
