The duplicate warning is currently an error toast that times out and goes away before i noticed it. This is especially so if you have notifications enabled and other toasts are displayed.
It would be much better to have a visible indicator on the entry screen. A simple DUP message or indicator would be a great enhancement. A fancy version would show the date/time the most recent log was entered.
The issue with that is the contact is already made and logged before I find out it is a DUP. Is there a way to make an error (DUP) message pops up that the call sign has already been logged so I can tell the contact that they are a DUP? Maybe like the drop blue drop down indicating the contacts name and/or the Green Park drop down? Maybe a yellow, orange or red drop down indicating the Call Sign I am entering in already in this log? Just a thought. Eric KN4UDL
