That argument falls apart when you compare to Emby....who is small, 1 to 3 person "team". They pretty much operate same scale as Channels DVR...yet, they have full web interface, desktop software, and apps on all platforms. And is a more mature home media software, that is their main focus, but does have Live TV/DVR abilty, that they have spent a great deal refining and it works very well. just, lack TVE support, sadly.
And yea, I too hope Channels some day have a desktop software app, and that maybe the web interface gets overhauled to work like Emby, in that it is a full featured app, but also has it "Manage Server" dashboard. that setup is what makes the most sense.
But, its fine as a strict administrative dashboard for now.
I am just fine using the Channels app on a stream device, but can for sure see the desire for a proper PC based app/software.
Maybe they can start small, and just make a Win Store app, (modern ui, metro)
Its pretty easy to make one of those.
