One things which as suddenly struck me as 'missing' (and maybe there are cosmetic additions planned in towards the end of the build...) is branding. There's no royal blue around the stadium exterior (I have no problem with this btw, the aesthetics are ace) or club badges etc.
There's nothing obvious which says 'this is Everton's new stadium'. The only real obvious hint that I can see which suggests which club are going to be homed here are the blue seats coupled with knowing what the dockside Liverpool skyline looks like.
I know in some of the original drawings, the word 'Everton' was going to be written across the glass panes (I wanna say on the North stand maybe?). I've seen that many videos, maybe there's something hiding in plain site, but do we know if there's anything like that to be put in at a later date
