The new UI library is reeaally awesome! Like super duper good (thanks Bas Brands )
But it has been crippled right out of the gate because it isn't easily discovered by dev's. It has made the same mistake as xhprof / tideways in that the admin menu item only appears when certain conditions are met.
I think this is a critical mistake and we should fix it asap - the menu item should always appear so a curious dev can see it and clicks on it to learn what it is, and then if the conditions are not met they should get a clear message with instructions or a link to instructions on how to get it working.
I'd love to even go one step further and get some sort of HQ policy around this type of dev tool (ideally all sorts of stuff not just dev tools) so that all admin menu items like this are never conditional so they get a foot in the door with devs, and it gets picked up in peer review.
(p.s. Did I mention how great this tool is??)
