This is the normal behavior of all waterfall displays I've seen, and is a very familiar screen behavior.
The cursor is the means of zeroing a signal of interest which then telegraphs the new frequency back to the K3. Part of the issue of tuning is that the saved information does not include frequencies outside the display, so tuning as you suggest would require filling in zeros all the way down AND further, performing a second graduated shift of ALL information. Given the very fine degree of detail stored, this may be a significant CPU intensive task using up processor cycles. Devil will be in the details, not in the simplicity of concept. 73, Guy.
