The process of rescanning the list of available serial ports (i.e. clicking "Rescan" in the New Connection dialog) is nearly instant. It is also quite common that the list of serial ports on my system changes between when I launch the app and when I want to open a connection. Having to explicitly click "Rescan" is kinda annoying.
Therefore, I think this dialog should automatically rescan the available ports whenever it is opened.
