I would like to have the smart oblique during manual flight. It could be very useful during the internal inspection of the building, for instance, an industrial warehouse.

It would be cool if whis would be possible when gimbal pitch is at 0°, and smart oblique capturing in horizontal way (for fascade photogrammetry)

Having this type of option would be very useful. Even DJI thinks so. Look at this email they sent out recently showing the benefits of facade/vertical scanning. The headline failed to mention that they had to use DroneLink for this flight planning.
