Yes. You can embed forms. See in my screencast - I’ve embedded a create-new-post form into a timeline update. 

Right now we stick to fixes, performance updates and fine-tuning. Any new features or modules only come if they’re part of custom implementations for X-plans and when we negotiate merging into core package. I would love to release JOT as soon as possible, but right now it would not be very prudent - we are getting close to a 1000 live sites working on UNA and need to make it as stable as possible
