Allow only one instance.

I'd like to have this option in the settings.

So everytime i open smartftp and it's already running, the existing smartftp will be just focused, instead of opening a new instance.

I agree - I would like to see this feature too.

I concur. There should be an option in SmartFTP what would handle multiple instances of the program. Caleb's idea would be very suitable for the default handling of multiple instances of SmartFTP.

Totally agree with this.
Make it so
