Absolutely.

Constraining AGC action to "fast, med, slow, off" really is a compromise of 
receiver ability.
Leaving it to the operator to change as needed is by far the best option 
for weak signal
DXing rather than having the 'wrong' AGC setting or having a fixed AGC 
value clip the
weaker signals (usually a problem when using 'fast' on CW on any 
radio).  Every signal
and every noise situation is unique and dynamic.

Yes - having AGC threshold available on the MULTI knob while not
inside a menu would be useful.  I have also suggested that more range
at the top end of the AGC threshold would also be a useful change.
Gary and the programmers are aware of these but I don't know
where they fall on the priority list.
