Just a minor point. When using Beta 1 and the new Dark Theme, I'd gone through the process of tweaking some of the colours. But now, having uninstalled Beta 1 and installed Beta 2, it would seem that all those changes are lost, and the studio defaults re-applied (I'm guessing they get written to a registry key that gets removed during the uninstall)

Not a big issue in the grand scheme of things, but it would nice to think the same won't happen come Beta 3, or RC 1, or whatever version follows. Or, if the same thing is going to happen, just a quick 'heads up' so I know not to make the changes again until the official release.
