How to enable dark mode on repl.it!? I don't have any option to do it
You have to enable 'explorer' via your account settings.
Just click on your name on the top left, click account. Scroll down till you see 'explorer', turn it on, then you will see a new setting that will allow you to enable dark mode.
Go to your name in the at the top of the left menu, click it, select account, scroll down to the
Preferences section, click the dropdown and select dark. If this is confusing, ping me and I'll explain it better
