I want to add as tooltip "Tip: end a line with <br> to start with a new line."
How to show the text "<br>" and to avoid that <br> leads to a linebreak in the tooltip?
Please update the new version of the extension Meta Box Tooltip to v1.1.3 to get support for this case. You can use the setting 'allow_html' => false to show the HTML code as the text.
Interesting... I have installed the AIO plugin, which was latest released om June 2nd.
I see that the Toolbar plugin you are referring to has release date June 3rd.
