CraftCMS has been getting a lot of traction recently. I haven't worked with it myself though.

Your best bet would probably be a managed wordpress solution, such as WPEngine, Pantheon or Flywheel. However many standard hosting providers have one-click WordPress installs and are usually cheaper.

That's most likely a zsh-plugin and not the theme doing that. Take a look at https://github.com/zsh-users/zsh-autosuggestions

I've been jumping between a plethora of themes, but have settled on Spaceship . Nice and simple.
