Yes, I know that.

No. E.g. I'm selecting frames for animation of a DEM. Consider the first 
frame - say height 1000 is too much and 900 too little - how do I know if I 
need 950, 960, 971, 983 or else? Now multiply this dilema by your number of 
frames. Fine tuning each frame height manually is uncomfortable and time 
consuming. Maybe it could be aided by a slide bar, where one would choose 
his height-step from between 1 up to this automatically derived factor 
depending on raster min/max.
