I'd like to suggest a + (add) that can be used to add certain call signs to a favorites pulldown. This list could be edited in the program settings. The pulldown would populate the Connect/Ping box, like the most-recent list does now - except Most Recent is dynamic, doesn't retain.
I contact the same calls regularly in VarAC, even if I don't hear them in the LH lists. I was just thinking it would be nice to have those frequent contacts more readily available.
