[JHV 2.1] feature request: add "play backward" button to "Movie Controls"

Add "play backward" button to "Movie Controls"

[Markus Langenberg (markus-langenberg)]

Hi! When you click on "More Options", you can change the animation mode. Setting in to "Swing" will cause the movie to go backwards as soon as it reaches the end of the movie and vice versa. Is that sufficient for you?

[Borut Podlipnik (podlipnik)]

Hi, no, this solution is not sufficient! Let say you have around 1000 frames
and
you see an event in the middle and you want to go back as far you want. This
is
only one example where will be good to have backward button. Yes, you can
also grab frame slider and pull it back...

OK, good to know. We will think about this request.

[Daniel Mueller (dmueller-esa)]

In my opinion, a dedicated backward button will not be needed if draggable start/stop sliders are added to the frame bar (bug #785080). With the latter, the user can define a sufficiently narrow time range and play this in swing mode. I would think that most users will want to alternate between playing forward and backward of short image sequences rather than playing entire movies backward. Overall, one of our goals is to keep the user interface as intuitive as possible.

Best,
Daniel
