I attempted to create a new component and forgot to give it a name, as that field is not visually obvious (the component language is much more visually prominent). I then tried to click on create and it was just disabled, without a visual cue as to why. It took me a moment to realize I had forgotten to give it a name.
Giving the name field more prominence (color, a textbox, highlight, etc.) and/or enabling the create button but giving visual feedback that a name is required would be helpful.
