The Gutenberg Inserter Panel contains all available blocks, patterns, and saved reusable blocks.
It offers a search functionality to quickly access the blocks you might be looking for.
Gutenberg allows you to drag & drop blocks from the inserter panel to the editor page. Cwicly doesn't recommend using this feature.
Cwicly provides a quick insert panel with every block that accepts child blocks.
When using the Quick Insert, we recommend clicking on the desired block. This will instantly insert it in the right position.
