Great theme, very tidy. My only criticism is that it would be great to add a slight (.02% or so?) overlay to tabs themselves so they're easier to manage. As someone who has a lot of tabs open at all times, figuring out the tab borders can be slightly challenging. Even better if this could be a customisable setting.

Looks good on smaller resolutions. On 4K fullscreen there is blue background overlapping nebula image.

The theme looks great on lower-resolution monitors; however, on my 4K monitor, the background doesn't fully extend to the left edge. Could this be addressed? Please let me know once this issue is resolved, and I would be happy to use the theme!
