This comment kind of scares me "Beta should be available with UNA10. " - We already know that UNA 10 is going to go through several Betas.. So, should we expect React Jot to be release with the UNA Beta on June 15th or did you mean that the React Jot Beta will not be available until UNA 10 final is released?  

This is great to read! It would be great to have access in Studio to the different UI components to build pages.
