Owing to having to set-up Vim again on my work machine, I decided to have a look around to see if I could find a better colour scheme than pyte, which I've been using for awhile.
It seems there are a few good dark background ones (I didn't find any other light background ones):
Of those I like IRBlack best, but I think I'll likely toogle between pyte and IRBlack as overall I'm definitely more of a light background guy and don't really get the whole "view on black" obsession.
I also went looking to see if the toolbar icons could be improved, because they are pretty terrible on Windows and was surprised to find someone had tackled this already, but I've decided to hide the toolbar as I don't really ever use it. So that solves that problem.
And note to self:
set guioptions-=T "remove toolbar colorscheme ir_black "set default colour scheme
