new version of this block includes an option to activate a “compact mode” in which the icons and text take up less space. The compact mode is ideal if you are using this block in a wider column because it takes up less space. If you have it in a narrow column it is better to deactivate the compact mode because the icons would be too small. By default this option is set to false, i.e. the compact mode is not selected by default.
Update is simple, just replace all files, all your settings is saved on the server and will not be affected. If you want to activate this, simply go back to your block setup and there is now a new option to enable this.
