@elly_cho Ah I see! I think I can understand how you feel but one thing I have learned is that quick iterations are sometimes better as long as you have a solid plan in place to get there.
I believe even the PH guidelines on launching mention that you can always launch major features and/or updates so I'd say go for it now! And whenever you finish that important feature feel free to do another mini-launch to unveil and share that as well.
