@tmconnect like i say at opening post: modify only the toolbar is not enough for me. thats why your post dont help. and if you read carefully you will see that problem is made by ACF, thats why i also cant use tiny_mce_before_init filter. that work for/with default wysiwyg.
@elliot any toughts, comment or help for this problem?
or is someone else able to help me, without to modify corefiles?
