Mike, this is a very reasonable comment, thank you!
First off, our Coming Soon project is available only by a direct link as of now, here it is: Coming soon: New amazing Elfsight widgets will be there in a short time!.
As for the idea of showing percentage of update progress, this is a fantastic suggestion, we even have a similar request in our Wishlist here: View the percentage of development progress for upcoming widgets.
The thing is that at the moment we’re struggling with releasing new features in a timely fashion (due to restricted resources), but we’re planning on working in this direction. I really hope I’ll be able to announce such a category on our forum one day 
Thank you so much for sharing your thoughts, Mike! It’s great to hear your feedback and ideas!
