An intuitive solution to make the default WordPress Gutenberg sidebar resizable.
When using ACF blocks in the sidebar, the default width can make editing difficult when there are a large number of fields. Being able to adjust the width is a huge help.
Great little plugin but the Ad when resizing is a little to much intrusive. Clients asked if the site was hacked multiple times. Yes, clients are not as tech savvy sometimes. Is there not a better place to advertise your other plugins?
The most important thing for me is that it works with WP 6.6, as another plugin solution that I had, stopped working with v6.6. So thank you very much for this plugin.
After developing for many years with gutenberg/blocks I can confidently say:
This is easily one of the most missing basic features for authoring experience. Shame this isn’t part of the core and kudos to the author.
OMG. How could Gutenberg have been released, ever, without this simple, little feature?! WordPress should pay millions to integrate this plugin in the next release!
Seriously. Took me years to understand the “logic” of how to move Gutenberg metaboxes from below the content to the right, into the sidebar. And back.
Together with this little plugin, the Resizable Editor Sidebar, this semi-ugly UX of Gutenberg begins to shine. Finally.
Thank you ever so much for all the efforts!
As of today, only 900 downloads. Unbelievable. Should easily grow to 9.000, 90.000, 900.000, 9.000.000. Let’s spread the word!
