This (though I agree with sibling comment about a few more being useful).

I reviewed 20 popular admin themes last month for our startup, and was v disappointed with them. Either due to code quality, or throwing in loads of useless widgets which are more consumer rather than business oriented.

There's a gap for a theme that's more like Stripe's dashboard, not these heavy-left-hand-menu dashboard themes. Or something like VMWare's Clarity Design System (https://vmware.github.io/clarity/)

Something corporate.
