Rotating relative to a POI.
What I would like for a panorama is:
- Fly to destination
- Turn towards POI "Bravo" ; Angle gimbal to POI Bravo or to the horizon
- Rotate counter clockwise & take first photo
- Rotate clockwise / Take photo
- Repeat step 4 as required
However if I create a path and set a POI marker at the end, the rotation step turns a set number of degrees from the incoming path, not from the POI. (Is this by design ?)
If I set a destination I can set the drone heading and Gimbal angle but I need to calculate these
It would be be better if add drone heading on a destination component had the option to aim towards a POI +/- a number of degrees and add gimbal orientation could also aim at the POI height (+/- a number of feet/meters)

It sounds like you just need to set an altitude offset on the POI. Can you post a mission plan that demonstrates the issue?
OK. I've found how you attach a POI to a destination :-) And I understand POIs a little better too. I hadn't grasped that a POI is tied to a component - I thought they were created once and referenced anywhere in the plan.
I can get what I want with a POI attached to a destination. When I rotate the drone after arriving at the destination with a POI, it rotates starting from the POI by the given number of degrees, which is what I need (and expect). But if the drone is facing a POI attached to a marker on a path it rotates to the path + the number of degrees.
The up / down arrows let you enter a negative number but the UI resets to zero if there is a negative number, so counter-clockwise rotation needs to bet entered as (360-degrees). It would be easier if either negative numbers were allowed or they couldn't be entered at all.
I can either angle the gimbal down by using height of the POI, or sweep out the panorama level with the horizon. I can't think of a case where I'd need a specific height which wasn't the POI height.
Can you post a mission plan that shows when you are talking about with "it rotates to the path + the number of degrees. ".
I had real trouble with this. But now I can show something which might be by design or might not
https://app.dronelink.com/james-o-neill/jamesshared/plan/SyuZoxBqPmDIEZRuXiry has simple path with 2 way points and a poi marker at the end.
Where will the camera be facing when it runs my "Pano" component ? You'd think it would be down the dotted line.
The drone has not turned when the Pano part starts. Even if interpolation is enabled, the motion to turn towards the POI only starts when the marker is reached, and before it has turned, the process moves on to the next step so it turns 45 degrees from where it is pointing: along the path
https://app.dronelink.com/james-o-neill/jamesshared/plan/LWxsXhB8jXQkWOwxAcPO adds a marker to that path. Both markers have linear interpolation on.
Now what happens is after passing marker 1 the camera turns to face the first POI, and starts to turn towards the second POI. This time, at the end of the path the camera is facing POI B.
If I use a destination with a POI then locks on to the POI at the start of the leg so it it will always be facing it at the end but POI isn't shown with a link to the destination . For example https://app.dronelink.com/james-o-neill/jamesshared/plan/dRl7iBO7i1xAoTOzrLSg
BTW ESRI has a bit of problem with the bridge , it's making the picture of the bridge deck follow the ground profile

shows it better. Not sure if there is a simple way to report that (obviously not your problem!)
This is by design. A marker with a POI and no interpolation means: once you get to this point on the path, start rotating the drone to point at the POI. By placing the marker at the end of the path you give it no time to actually complete the motion. A marker with interpolation means: interpolate from a previous marker with a POI, in which case there was none so there was nothing to interpolate from.
