This plugin looks great and fits right into the WordPress UI. It looks like it’s part of core and I think it should be. The plugin provides the missing piece needed to build sites with ACF blocks using the preview option rather than editing directly over the block. With this plugin, we can setup a WordPress editing experience just like all of the other popular CMSs out there. Editing can happen from the sidebar because the concern about space is solved. The plugin allows users to quickly resize the sidebar just like other CMSs allowing editing to happen in one area, not all over the place. This plugin is truly the only way to create a great live preview experience with WordPress when using custom ACF Blocks. Same for blockstudio. All of these blocks require the sidebar and core has no way to resize. It’s a shame that it takes a plugin like this to hold it all together. But I’m grateful it exists!

Does the job really well, I just wish it would remember my preferred size. It is resetting to the default size with a page reload.
