Feedback on the new themes

More room for customisation is great, but none of the themes are exactly like the old one, they're all slightly worse in different ways. I don't like the lower contrast of Ash at all, it makes the app much more unpleasant to look at, and the others are all even worse to me. I also really don't like the rounded corners everywhere, they look kind of outdated, but if that's staying at least give an option for the better colours.

If we're doing themes, please either offer one that looks exactly like Discord before this update (which was great! I liked it!) or allow for more granular adjustment of each colour.
