Instant Seek - helps instantly find your favorite scene. Instant Seek by dragging play cursor to access the exact scene you want quickly.

Here is a good examples:
WebM (1280 x 720)
MP4 (1280 x 720)
MP4 (4096 x 2304)
MP4 (320 x 256)
MKV (1920 x 816)
AVI (720 x 576)

Splash already have preview window... The only difference - it updates only when cursor stops. Since Intel QuickSync is hell fast at decoding (like 400 fps for 1080p) it would be nice if it would update continuously.
