Four network connections active at the same time:

• 3G connection (etisalat USB modem)
• 2 wireless networks with 2 different wireless cards (the internal card and another external one)
• 1 wired connection

This is EXTREMELY useful and I gained a lot of benefits getting connected to multiple networks at the same time and being able to direct the network traffic to its destination using proxies, check the screenshots below:

Note that there must be one default connection (that can be changed manually since version 0.7.1) that all the traffic go to except if else specified.
