All the search bars I've dealt with are linear, which is a pain when you want to do major leaps, or minor nudges. Usually I have to resize the window in order to get the amount of jumping that I want.
It would be nice to have a search bar that moves the current position in a media file little when
you move the cursor to a point close to the current position, and a lot when you move it far away. This would be a logarithmic search bar.
So, if you want to jump ahead little tiny steps, you click close to the current position indicator, and it moves a little bit. So you have fine control when you are close to the point that you want. However, if you want to jump ahead a lot, click far from the cursor.
The end result is that the closer the current position marker is to the point you want to be at, the less it will move when you click near it.
