Not enough contrast at the top to read tabs and tell tabs apart. Also very hard to see URL with this theme.

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!
