@Wikunia @TheCedarPrince And with a new PR a new interface question.

I am going similar to JavisNB with the equivalent of embed being stream the question is I am moving the liveview=true option into stream and entirely out of render, or at least that would be the plan. Is this a good idea or do you prefer the possibility to call liveview from render itself? Perhaps the best is having it in both render and stream acting in the same way?

Let me know what you think!

[Wikunia]

I think I would use a liveview function which works similar to the embed function. No need for a liveviewer keyword anymore. Stream sounds more reasonable to me when we have a stream to twitch functionality or something like that.
