It's the price for decentralization I guess, same applies for BitSquare. I'm not sure If the same features like choosing the ports, connecting through Tor etc. can be applied If they made a browser-based platform, maybe It would be If you run it locally yourself but in that case, that would be more work then installing an app/software.
