This plugin hasnt been tested with the latest three major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.
Thank you! Nice and lightweight plugin.
Please add a description with a link to the list of global blocks below the Blocks dropdown. This would make it easier to create new global blocks if needed.
Also i would expect the block title is used as widget title but it is not. Will you that please?
