[Elecraft] K3: All-mode squelch suggestions

[KM5Q]

Based on FW 3.04, here's what I would like to see, so I'll toss it  
around:

I would like a timed decay, so when the sound goes off, it doesn't do  
it abruptly, but with a timed decay. This will make listening more  
pleasant, less choppy.

I'd also like ability to CONFIG a squelched volume to something more  
than zero, so it would still be slightly audible.

In SSB mode, adjusting the SQL shows the setting numerically on the  
VFO B screen. In CW mode, it does not. I'm not sure I care, but I  
don't see why it shouldn't be consistent between those modes. There  
could be a CONFIG to choose whether to see it on the screen or not.

Good work!
