In the new update 0.12.0 haruna added thumbnail preview support. But IMO it may be lacking on some important UX aspects.

Firstly, when skimming through a video using the seekbar the the frames won't update. If my language is unclear (sorry) see the first attachment. 

STEPS TO REPRODUCE
1. Open a video in haruna.
2. Drag the seekbar with mouse.

OBSERVED RESULT
1. If the video is paused and you drag the seekbar, the video will be stuck on the same frame.
2. If the video is not paused and you drag the seekbar, the video will keep playing without updating with the seekbar.

EXPECTED RESULT
The same way mpv handles it. Whether the video is playing or paused, if a user is dragging the timeline in seekbar, the frame should update with it.  

Secondly, the thumbnail preview only work on hover, but not while dragging

STEPS TO REPRODUCE
1. Open video and hover over the seekbar, you can see thumbnail.
2. If you skim through the seekbar the thumbnail won't update.

OBSERVED RESULT
Thumbnail don't update when skimming.

EXPECTED RESULT
Thumbnail should update with skimming.

IMO, youtube does this pretty well, attachment 3 [details] shows how youtube handles it.
