"""
Processes HTML content by removing unnecessary tags, minifying the HTML, and extracting the title and body content.
Args:
html_content (str): The HTML content to be processed.
Returns:
str: A string combining the parsed title and the minified body content. If no body content is found, it indicates so.
Example:
>>> html_content = "<html><head><title>Example</title></head><body><p>Hello World!</p></body></html>"
>>> remover(html_content)
'Title: Example, Body: <body><p>Hello World!</p></body>'
This function is particularly useful for preparing HTML content for environments where bandwidth usage needs to be minimized.
