Ever want to tweak the appearance of the WordPress admin pages by hiding stuff, moving stuff around, changing fonts, colors, sizes, etc? Any modification you may want to do with CSS can easily be done via this plugin. Using this plugin you’ll easily be able to define additional CSS (inline and/or files by URL) to be added to all administration pages. Hooks are provided to customize the output of the CSS, the CSS files, and if/when the CSS should even be output (see Hooks section).

Upgrade to WPMasterToolKit Pro External services WPMasterToolKit does not connect every website to external services by default. Some optional modules can communicate with third-party providers only when you enable and configure them, for example SMTP and email providers, social login services, geolocation databases, vulnerability data sources, analytics platforms or AI services. The data transmitted depends on the selected module and provider. Review the module settings and the provider’s terms and privacy policy before enabling an integration.
