Hi @sajithdevidas
You can find the custom style config file at the following location:
win10:
%appdata%\\gui-guider\\{version}\\preset_record.setting
Ubuntu:
~/.config/gui-guider/{version}/preset_record.setting
MacOS:
~/Library/Application Support/gui-guider/{version}/preset_record.setting
The current version does not support the import and export of preset style, We will add this feature in a later release.
Best Regards
Liubin
