Hi, I often use my phone to listen to radio shows or videos and frequently have to rewind by a few seconds to replay a part I did not quite understand or hear clearly. On the video player I use, the arrows can conveniently be set to fast-rewind or fast-forward by increments of a user defined time (1, 2, 3, ... 5 seconds, etc.) on the file that is being played. This makes replaying much more ergonomic than using the progress bar. Currently, the fast-rewind and fast-forward arrows are set to go to the next file on a list. Would you please consider to enable users to define the effect of these arrows? Thank you, in advance, for your attention.
