I decided to make the min/max range fixed because for some cases waterfall looks too noisy (when whole dynamic range of the signals is not so big).
I guess it worth to add some configurable offset for spectrum/waterfall, when these levels are auto.
BTW, I'm thinking about merging auto min and auto max for waterfall and spectrum - it will be one switch (auto level), 2 levels (min/max) when auto levels is off and single level (offset) when auto levels is on. What do you think?
