I wish he built a "Edit a form in a slideover". Modals are already part of the core_components and the Phoenix team has done a good job of covering edge cases around CSS transitions. But slideovers have one aspect that's not well covered in modal flow: in/out transitions. Slideovers have a slide-in effect when they are invoked and at the end of transition load the form component which is a live_component. When you cancel/close they slide-out along with the form component. At the end of the transition is when you want to remove the live_component from live_view. Handling these transitions with live_components is very tricky.
