Im new to using Sublime Text (which is evident from the question I am about to ask).
How do I get a directory window to show up on the left of the editor to view files/folders I am currently working in?

Thanks

Project > Add Folder to Project

Thank you!

Is there a way to change the background color for the sidebar?

Yep, check out “Themes”.

Package Control will help you install them.

Thanks!
