Block Options for WordPress Gutenberg Editor is a brand new plugin that allows you to manage each block's visibility per mobile device, tablet and desktop. You can also restrict display on user's logged-in or logged-out state; and if you are comfortable with WordPress conditional tags, you can use display logic option. Making your Gutenberg blocks management easier is Block Options' main goal.

This plugin would be really useful for Gutenberg users, it adds extra (much needed) functionalities to the new WordPress editor. I specially love the device visibility option.
Pros:This looks super useful for the upcoming new WordPress editor. This will add much needed controls to each block level.
Cons:Can't think of any cons just yet.
