@st_albert...My grateful thanks for confirming that the plugin works on Linux.

I also had a re-think about your <i> <b> <u> question. You could certainly do it with S&R as you suggest. But it would also be very easy for me to change my plugin to to get rid of these <b> <i> and <u> tags and replace all of them with their <span> equivalents in the html file.

Here's a code example of how to do it using bs4

Spoiler:

html = BeautifulSoup('html_file_text', 'html.parser')

search_tags = ['i', 'b', 'u']
for tag in html.findAll(search_tags)
   if tag.name ='b':                     
       tag.name  = 'span'
       tag.span['style'] = 'font-weight: bold;'
    
   if tag.name = 'i':
       tag.name  = 'span'
       tag.span['style'] = 'font-style: italic;'
    
   if tag.name = 'u':
       tag.name  = 'span'
       tag.span['style'] = 'text-decoration: underline;'
