I think we should use the one from codesandbox ci, that one also has the shadow.

Can you ask Danny? He told me to use this one

@CompuIves this is not the rounded version.
As far as I know the rounded version bas created is the new one.

I removed the "shadow" side because of the legibility of the icon

[CompuIves]

Hmm, in my opinion I think this looks actually better:
. Maybe it's because of retina? I can clearly see the shadow when visiting ci.codesandbox.io. I would argue it would be pretty hard to spot the rounded corners actually, but no strongly held opinions. We can also go with this one.

Can we give this one a dark outline as well? This way it shows well in all browsers + on all backgrounds.
