We currently do not have a timeline for version 2, but we are already collecting ideas. New features are implemented into the "main" branch every now and then.
You can find the complete list of ideas in our wiki: Version 2 Brainstorming.
This list is not exhaustive. The wiki page should be regarded as the primary source. Feel free to tell us about your ideas on the mailing lists!
