A block that generates a random “Powered by” message. It is meant to replace the typical “Powered by Theme/WordPress” message in footers but can be used anywhere.
Some examples:
<ul>
<li>Powered by coffee.</li>
<li>Powered by crazy ideas and passion.</li>
<li>Powered by heart and soul.</li>
</ul>
The default messages are shown in plain text, but you can “emojify” them, like so:
<ul>
<li>Powered by ☕.</li>
<li>Powered by crazy 🤔 and passion.</li>
<li>Powered by ❤️ and soul.</li>
</ul>

Powered By Block

A fun block for displaying a random "Powered By" message.

Qubely – Advanced Gutenberg Blocks

This can be a huge hit in WP plugins directory. It is a great plugin but giving 5 stars because this plugin is missing basic functionality like adding custom fonts, custom shape separator for sections etc. 

I understand that plugin is in development phase. At least plugin developer should write provide a clear documentation for developers with a list of available hooks/filters but unfortunately they have not written any documentation yet. 
From this, it seems that their motive of providing this plugin free here is to lure users to buy premium version and support. 

Great Plugin - But need a lot of improvements

Readymade gutenberg blocks and sections with rich customization options. Enhance Gutenberg editor with easy UI and functional blocks.
