Well, christmas-eve is near, so here is the present.
i just released a new version of the proxy server which also can do all the work for the (initial) sideloading of the app from @Orca.
Grab it here: https://github.com/kadrim/proxy4plex
For those of you, who already use the proxy, you would not really need to upgrade. It helps new adopters who want to sideload the app on smarthub, but have problems with that.
So the only new feature is sideloading
What does the proxy do while sideloading?
It downloads the last release from @Orca (see Link above) and modifies the zip-File to prepare it for network-sideloading. If requested, it deploys the app.
No more need for USB-Pendrives or using sammywidget to deploy.
Follow the (updated) instructions on github on how to setup your TV for that.
And as always: enjoy!
Stay safe and sound!
