Bug Description

I many cases I get an bent panorama and trying to use the "straighten" function (from the preview window) doesn't help. For now, the only way is to insert horizontal points (for each picture), but this takes long time.
A faster way for linear panoramas would be to be able to draw a curved line (of the bent horizon, using some control points) and try automaticaly to straighten that line. One way would be to modify the picture's parameters and the other way would be an post stitching "unbend" image function.

I uploaded an example mock-up of the manual straighten function.

Hi, yes it would be nice to be able to manage horizontal and control points in the preview, but there are some alternatives that you might not be aware of:

It is possible to add horizontal control points that span different photos, so you can do what you ask in the Control Points tab.

You can straighten manually in the Fast Preview window in 'Drag' mode, drag the panorama so any part of the horizon is in the centre 'crosshairs', then right-click-drag to rotate the panorama until the horizon is level.

Alternatively, if there are vertical features in the scene, drag the panorama so one of them is over the 'crosshairs', right-click-drag to rotate the panorama until this feature is vertical. Then shift-drag the panorama until the second vertical feature is vertical.
