Support for more powerline separators
Would be great to see full support for different glyphs provided by nerd font for powerline. 

Some examples and a list of glyphs are here: [https://awesomeopensource.com/project/ryanoasis/powerline-extra-symbols](https://awesomeopensource.com/project/ryanoasis/powerline-extra-symbols)

Or, please indicate how someone can customize this in their config.

Thanks!
