Why bake libtransmission into the app instead of just using the transmission daemon's RPC?
What you've done actually makes it harder to use, because in order to configure any of transmission's settings (ports, connection/torrent connection limits, bandwith limits, etc) the user needs to dig around to find the transmission config folder and then manually edit JSON with a text editor - because your client doesn't expose any of transmissions numerous settings [1] to the user except for choosing the download folder.
I'm not sure why anyone would want to use this instead of Flood [2] or even old Transmission Web Control [3]
