Hi,
thank you for your kind words.
The eon system - which I really like btw- uses a proprietary mechanism for fast forward and rewind. It quickly loads these preview pictures which it displays and then jumps to the mark once you stop forwarding/rewinding.
Kodi to my knowledge does not have such a mechanism with preview pictures.
I was thinking about if skipping like for seconds and minutes could work but I didn't investigate any further so far...
