Lets not forget that each button on the device now has an assigned function.
So if we added a hold button, which hardware button would we use?
Then if we did have a hold button, how would we now add the nuisance delete button? I guess long hold for one and short press for the other.
My thought for user delay is a drop down menu of 1 through 6 seconds. Add it to D-4 Group ID setting menu. This way when the ID is landed on it would use the time delay to hang based on your selection.
Hey Unication, if you end up doing it that way can i get a free G5. LOL
