I really like the fact that Ignite (Dark) color theme for the GUI is now a reality.
Unfortunately, to me, dark modes interfaces are gray scale based and I'm not a fan of the actual dark blue interface.
Please consider to allow users to customize or create their own Color Theme either by editing a config file or better, by using a windowed interface with real time preview.
(If a config file or a registry key set already exists, I'd be really interested to know more about it.)
