I really like this asset pack as it is very rare to see Godot themes, I hope you do some more. One thing that would be very nice though is if you were to put your theme(s) in some sort of organized folder strucuture. I would suggest something like:
res://Deakcor/FuturisticTheme/<all files here>
That would make it very easy to copy your theme to different projects without conflicts and also if you do release more theme packs later when copied into the same project there would be no conflicts.
As it stands I ended up having to open your godot project, copy the theme and all files to some subfolder so godot would update references (fonts didnt work), copy over the fonts and update references, then copy it into my own project.
