Note: This plugin is maintained and hosted externally on GitHub.
It creates an extra tab in the style editor with a graphical style editor.
The GeoStyler is a set of JavaScript packages that can be used to edit and convert various style formats.
When editing a style in the GeoStyler the SLD code editor is automatically refreshed and vice versa, so you can just edit the style and then apply/save it as usual.
If you run into trouble using the GeoStyler module or have some suggestions feel free to open an issue in the GeoStyler repository.
