This is was a request or suggestion to add gallery the scene that we already completed, and gallery available when the last gameplay. 

I don't know what I'm saying but, you guys sure knows what I mean right?. 

And also, when android version is? 

There is a Gallery Mod available on the Discord. An official Gallery will be considered for 2.0, time permitting, but community feedback was for the developer to focus on Story. If no official one is possible my hope is the Docs's gets added as toggle option within the menu. 

Android release is pretty much a no at this stage.
