Name: transmission-remote-gtk
Homepage: https://github.com/transmission-remote-gtk/transmission-remote-gtk
Why: The current transmission package does not allow for remote connections, which is quite common for those using transmission as a daemon on a nas or home server. This allows for those connections. I think both should be able to be installed at the same time.
Open source: Yes, using GPL-2.0
How many users: Anyone who runs a transmission daemon on their home server or nas.
I've also created a yml file for it at https://gist.github.com/stobbsm/975e4c9126bc99587a03220e86888134
