print a helpful breadcrumb when we print the chooser

This makes it easier for users to take the fast path / single pass

The tip should only be displayed if it takes more than a few seconds to parse the capture file(s). Something like 2-3 seconds.

Please add a newline before Opening /srv/wifi/home-01.pcapdump.

What is the purpose of displaying the essid and bssid again after selecting the network as well as the amount of potential target (which seems incorrect in the first output considering there are at least 675 networks)?

Feedback for the user in case they misread the number, or so they could -e or -b .

amount of potential target (which seems incorrect in the first output considering there are at least 675 networks)?

We don't have to print that, but it is the number of networks that matched BSSID or ESSID (for multi target support)

[aircrack-ng]

Let's remove the ESSID/BSSID printout.

For potential target, just add a warning if there is more than 1 BSSID that match the ESSID provided (it's up to you if you want to provide the list of BSSID)
