I can drag the playhead with the mouse to the general neighborhood I want, but from there it is tedious to positioning it exactly. If I hold down one of the left/right buttons, it zooms to the beginning or end of the video. I can’t drag it with the mouse in small increments, and the left/right button clicks advance by a single frame, so it takes a while to go a few seconds in either direction.
Could you change it so that holding down the ctrl key while clicking on left/right buttons advances by a whole second instead of a single frame. Likewise, you could make the shift key advance by 10 seconds.
