After releasing 1.4, we are currently in the planning phase for vNext. Once we have a more solidified plan in place, we will update this post.
PLEASE NOTE: We are working on these items based on this priority order, but this is NOT a commitment that all of these enhancements will make the next release. We are working on a number of other smaller features in parallel. If you have comments or questions on any of these items (e.g. how would it work?) or would like to be included in a preview demo, please let us know!
