  • Very powerful and useful, especially for complex projects

    This plugin really helps close some key gaps between Gutenberg and Full Site Editing. For advanced users who are making the switch to FSE, it really is a must-have. We've used it significantly cut down on the time and resources it takes to build custom blocks.

  • Grate plugin and mess at the same time

    5/5, but some words worth to put:In general experience: I love... few things - the rest is just mess I can't even as a developer to turn off.What I love / like: Grid Block - it's almost perfect and far away from other plugins offer the same I can develop features NOW that comes in next few releases to WordPress (like: lock binding, easy pattern creation etc.) What I really hate: Pattern library: it could be add-on - not bundled thing in this plugin - for infos for devs like CBB button in toolbar could be a filter to turn it off. Disable native plugin's blocks like carousel - for now it's possible by another plugin installation (with some random problems). Freemius - I understand it, but still it's the only one plugin I use and contains "Freemius" inside. Maybe it's worth to switch to own flow (i love the Misha did it and has tutorials how He made it: rudrastyh.com). Best,Paul
