Is it better after 5.11.4 release?
It says:
5.11.4
Release Date – 2nd December 2021
Fix – Fixed several Select2.js conflicts with other plugins
Fix – Fixed an issue where block name sanitization could change valid block names containing double hyphens
Fix – Fixed an issue where blocks with integer IDs could fail to load example field data
Maybe it would be a good idea to make this open-source after 2022, so the community could keep contributing to this plugin.
