Small Feature: Further Improve Dark Mode Aesthetics

Dark mode looks phenomenal :) Thank you very much for that. However in certain menus, some of the buttons are bright white against the dark background which contrasts too much with the UI. Can we add a feature option for dark themed buttons that are a darker grey so they would contrast well with the rest of dark mode? They don't have to be as dark as the rest of the main windows on the UI but darker buttons (such as rgb(190, 190, 190) would look better)
