Sidebar File Selection Too Bright

[samjross]

I absolutely love this theme, let me say that first. Beautiful, gorgeous, almost perfect.

That being said, the bright blue in the sidebar to indicate what files are open is much too bright. Very distracting. You've improved on SODA quite a lot, but this is one thing Soda did right. They let the sidebar just be grey.

I'd like to see an option or an easy way to change the sidebar to have highlighting be a different shade of grey rather than blue.

fixed with this fork that I've made a pull request for #81
