Martin,
If you are referring to the condition where one or more pictures
appear rotated in the Control Points tab AFTER you have performed some
level of Optimizing then you in fact have one or more errant marked
points that have caused Hugin to rotate the images. For that situation
the optimization process determined the best fit to minimize the
errors between all the points is with the images rotated as you see
them. You can bully the images back to how they should be by adding
enough good marked points, but you really should find and delete the
errant marked points. That task is something you need to learn how to
do. In time you will learn what parts of an image are likely to fool
the automatic point generators. Sometimes it is best to manually
enter all the marked points associated with the rotated picture. To do
that you probably will want the picture properly rotated in the
Control Points tab after it has already been improperly rotated by
Hugin and after you have deleted the marked points for that picture.
That rotate task is what I think you are asking about and it sometimes
does make sense to have the ability in the Control Points tab but you
must realize that Hugin has evolved bit by bit over a long time. The
location where you correct the rotation is back at the Images tab and
that tab and its place in the intended work path scheme is much older
in the programming evolution. I suspect asking for the rotation
function at the Control Points tab may be considered heresy.
Rotating pictures is simply accomplished by manually changing the
"roll" value in the Images tab for that picture. Select the image in
the Images list and then type in the new roll value. Pictures appear
90 degrees clockwise rotated in the Control Points tab when the roll
value is 45 or greater. Pictures appear 90 degrees counter-clockwise
rotated when the roll value is -46 or smaller. Similarly, pictures
appear upside-down when the roll value is 135. Note that the roll
value is recalculated when you Optimize again. You pictures may flip
again if the errant marked points were not removed.

And if I want to keep already marked points, but since those two
pictures in Control Points tab are rotated differently to each other
(say 90 degrees), I want MANUALLY rotate one of those pictures.
Will this be possible someday?
Just to remind: I do NOT want to rotate whole panorama, but just one
picture when marking control points.

Now I'd like to know if there is a way how to rotate picture at
Control Points tab.
Hugin displays your photos the right way as best as it can.
Initially
it uses the EXIF metadata, but once you start aligning it uses the
rotation of the photos in the panorama.
If your panorama is upside down (which Hugin is happy to let you do,
it doesn't 'know' anything about gravity), the images in the Control
Points tab will be upside down too.
