To create a theme quickly and with fewer bugs, I decided to use the method:

[MerlinTheCodemancer]

The tactic is to take the theme with the closest style to what you want/want, make a copy and change the name of both the folder and the files in the following directories "At least those were mine"

.config/hyde/themes
.themes/

{Example theme name: Customization_Default}

for the new theme style Copy custom and modify in: .themes/Customization_Padrao/index.theme # so that it can be recognized by the pc
Edit files in : .config/hyde/themes/Customization_Padrao to modify colors and styles to standardize themes in ".themes"
and to add images and/or gifs just add them to the wallpapers folder
