That took a while, didn't it? Well I've finally gotten something that should be in the realm of usable, but don't get your expectations up too high. I just wanted to post this update so anybody that wants to test the new features can do so.
You can get the latest nightly builds here
under artifacts (You'll need a Github account), make sure to click on the latest run. Specifically this one
for now. There's both a linux and windows version and the presets. You still have to install the plugin manually, but I'll try to make an installer soon™.
The main feature is the config tool (in the folder cct), networking (transferring input from gaming to streaming pc), input filtering (white/blacklist certain windows), better gamepad support and some other stuff, though as I said this is a test version so expect half of this to not work at all and the other half just barely.
