My team and I started porting the CKEditor Blocks module, but then noticed that it requires CKEditor 4.3 https://www.drupal.org/project/ckeditor_blocks.
The CKEditor module for Drupal 7 seems to use 4.17, but apparently it is possible to "Install version 4.3 of CKEditor full source. See the CKEditor module for more details."
BackdropCMS uses CKEditor 4.14 (as far as I can tell so far) in core.
Since CKEditor is included in core, I'm skeptical that it will be possible to use the 4.3 version. Which also makes me wonder if it will be possible to port this module at all?
Any thoughts or advice?
