Yes I had attended the event.
The inter-city trip planned is releasing with the new app, probably by June (they said it’ll be much before July, same with Atherstack 6 release).
Along with the new app UI, I’d expect them to change the way you enter stops. I agree currently it is a pain to add stops especially when sharing locations from Google Maps/WhatsApp
And intercity planner will anyways help with long trips.
