I am using an older version of Bike 2 regularly but lost track of the changes that are usually announced on the forum for each build. There there are certainly folks around who monitor the development closely and also create extensions. For me, as an user with rather unsophisticated needs, it would help to have a summary on the current state of Bike 2 and what is possible (blog post, demo videos).
For me it would be e.g. helpful to know if I can mimic TaskPaper behaviour, where I relied on filtering by line using different tags/tag combinations.
I will add this thread here, as i asked the same question recently and have been greatly enjoying all the improvements since my last checkin several months ago!
