I acknowledge this will be a problem for user on-boarding. The editor is designed for repeated and extended use, and assumes you will use keyboard shortcuts instead of menu/widgets. I would love to get some ideas how a perfect first-time experience should be like. Or things you are looking for in an editor. Should features have dedicated on-screen buttons/icons !? I've been thinking of maybe adding a dashboard with cool looking graphs showing website visitors, etc, to make it look more attractive ...

I've now made a dark theme!

demo: https://webide.se/?darkTheme

Is this any better ?

It will automatically activate on Macbooks when running dark theme. But on other platforms you will have to append the query string.
