Themes are just one customization you can make. There are many more!
Go to Preferences ➤ Settings (also reachable via cmd ,) to see them:

Everything is highly configurable, and it’s sometimes hard to make sense of it all.
Some nice configuration options I set in my VS Code:
- Workbench › Side Bar: Location “right”
- Editor › Minimap: Enabled: false
- Explorer: Confirm Delete: false
- Explorer: Confirm Drag And Drop: false
- Files: Trim Trailing Whitespace: true
- Editor: Quick Suggestions Delay: 0
You can experiment and read about VS Code a lot. Everyone has different preferences.
This is also the place where you can change the editor font.
I like the DM Mono font. Fira Code is cool too. It’s free, and has some very nice programming ligatures, which transform common constructs like !== and => into nicer symbols.
Enable it by installing the font on your computer and then set the Editor: Font Family preference.
