This is an addon for the Block Editor Customiser which allows you to hide core blocks in the Editor. 
Please be aware it is possible to make them visible again if the user has access to the ‘Show more tools and options’ 
menu where they can select the ‘Block Manager’ to reactivate the blocks hidden by this addon.
If you do not want this to happen the only way of preventing it is to hide the ‘Show more tools and options’ menu item which can 
be done from the main settings page in the Block Editor Customiser.
If you want to deactivate or uninstall this addon, then please uncheck all block types that have 
been checked, save the changes, and open a post or page before deactivation, otherwise any block types that have 
been previously hidden will remain hidden unless displayed using the ‘Block Manager’ mentioned above.
** NOTE: ** This plugin requires version 1.6+ of the Foxdell Folio Block Editor Customiser to work.

This plugin allows you to customize the logo on the WordPress login screen. There is zero configuration. You just drop the logo file into your WordPress content directory, named <code>login-logo.png</code> and this plugin takes over.
Note that you should use a transparent background on the PNG image, crop it tightly (no padding pixels) and use a width of exactly 312 pixels for best results. Wider images will be downscaled in modern browsers, but it isn’t recommended to rely on that.
This plugin also works in the <code>mu-plugins</code> directory.

Login Logo

Customize the logo on the WP login screen by simply dropping a file named login-logo.png into your WP content directory. CSS is automatic!
