How it coming? Hope you feeling better. I’d like to see this working too, I have a use for it right now but it doesn’t work because this theme uses h4 tags.
For those who need it to work, and don’t want to wait for the update, I figured out there is a very simple style sheet in the plugin folder that you can change each h3 to the tag your theme uses. That fixes the first bug, but if you have the other bug with how different themes write the html/css, I might look into it at some point, especially if I need to use a theme that triggers this problem.
On a side note, another bug, it not only removes the title but it also removes any other headings from the widget content that match. The main reason I wanted to use the plugin was to hide the default title and put a different one in the content. Specifically, the headers are left-aligned by default, but I have one widget I wanted to center the title, so I used this plugin to remove the title and added the heading in the content inside a centered div.
A suggestion, instead, add a class to the widgets first header, and hide that class. Might solve all the problems!
For others with the heading in the content problem, it is a little messy, but I added a class .unhide with display set to inherit, and added the class to my headings in the content. Works for me!
