2019.3 alpha on the left, 2019.1 on the right. With the old icons I can see instantly at a glance what's installed and what has an update available. The new icons look exactly the same at a glance. Why would you do this?! Also: I think the new wireframe cube icon in the hierarchy is a really bad idea - it is so much more painful to look at than the shaded cube we had in earlier versions. It has the same color and stroke-width as the text - and that's bad because an icon should not look like the text next to it. Other than that I'm willing to give the new look the benefit of the doubt Maybe get your UI guys to have a good look at Rider - they're doing a decent job at making a flat UI work for a complex interface (colored icons for important things, monochrome icons for secondary stuff, etc.).
