Updating from 2019.2 I can't help but think that the new editor look is bland. It's also worse for UX as I'll expand a little bit further below. If 2019.2 came after 2019.3 I'd be happy for the substantial GUI update, but as it is, it feels like a large step backwards. The new icons for GameObjects look like the kind of cube that I used to draw with the line tool in Microsoft Paint when I was 5. Text on the Inspector is more difficult to read (my eyesight is not perfect) because it's one kind of gray over another kind of gray. A lot of contrast was lost. But the Project and Hierarchy tabs, as well as the values on the Inspector still use black text for some reason? It's not even consistent in being bad. The icons for models are barely different from prefabs. I won't pretend for a moment that the previous "sheet of paper over blue cube" icon made any logical sense, but it was at least easier to tell apart at a glance, because the sheet of paper was large enough and it had a bright color to stand out. I have to stop and take another look for this one, they're so similar. Scene icons are also bland, like you dropped the white layer from the old icon and made the black part gray instead. The icons for folders is literally just the outline of the old one filled with a black color. Again, the entire thing is way lighter and half-blends into the background. Buttons are also losing visual cues, for instance the "Generate Lighting" button/dropdown on the Lighting tab, although not perfect, at least had a visual cue in the form of a small vertical line that it functioned both as a button, on the left side, and as a dropdown menu, on the right side. Additionally, dropdowns had an "up/down arrow" icon to further differentiate them from this button. In 2019.3 "Generate Lighting" looks literally the same as any regular non-button dropdowns on the same panel, with absolutely nothing to differentiate them, yet it still works as a button if you click the text, unlike the other dropdowns that now look the same, which open a menu.
