Install style schemes from preferences dialog
I think it's not a big problem. You may consider it for the next development cycles.
gnome-text-editor comes with 8 different appearances. It should be good to have an appearance import option for the editor.
I think, the Dracula Theme (https://draculatheme.com) team would like to create an appearance for the gnome text editor.
It is a request but, could you consider naming the appearances? I have no idea which one is which.
