It would be useful to me to have a manual, per-input gain "offset" control for the receiver.
The offset would be display only - I wouldn't want it to actually affect the operation of the receiver.
For example, I currently do a lot of 160m work with separate TX and RX antennas, which
is quite common for weak-signal work on the low bands. Antennas like pennants, loops, beverages and the like all have "negative" gain, but much better SNR's than the transmit antennae. If it were possible to dial in a display offset for the receiver, (say +,- 30 dB) my given signal reports would be much more in-context, and there wouldn't be huge visual offsets in the noise floor when switching between antennas.
As a side note - other than some missing features, one of my few gripes with SmartSDR as it stands is that the panadapter is "fiddly". Change bands, antennas, or even between RX and TX when the RX has a high noise floor and I find myself fiddling either the baseline or the spread.
Oh yeah - one other gripe is the S-meter. It's fine the way it is as tied to the slice, but a separate one (like Bob's) in its own window that included an easily reset peak-hold and a sub-scale in dBm would be peachy.
