I was one of those Developer who felt weird closing the Sidebar in VSCode I always needed to see my files all the time for some reason even if this made no sense while working on a problem, but one day I decided to start closing it while working on a feature/problem and it was hard for me for a few days but after I got used to having a closed sidebar my productivity skyrocketed.

How do I start?

I find what I need to work on and open multiple tabs side by side when needed then I close the sidebar and start working.

Another pro beside productivity was my eyes hurt way less and themes which where to noisy in colors for me and I couldn't use them are now no problem anymore and I enjoy them now.

Hope this will help some devs out there.
