Very beautiful looking theme. I love dark themes with neon or bright colours and bright, colourful texts and symbols that offer a good contrast so they are easy to read / recognize as a contrast to the background image of the screen. At least on small screens. It looks very good on small/low resolution laptop internal displays like 1600x900 or smaller. I would love if it would also look good on higher resolution screens than that. On bigger displays (like 2560x1440 or bigger) there's a big grey fringe on the left side. Vesperexa do you think it is possible for you to make an update to some of your themes for high resolution screen usage!? I made an theme collection to share themes I personally like with others. I would love to add some of your themes to it, without having to add a disclaimer that they only work as intended on small screens.

Here is a link to my Themecollection:
