Create a plug-in or modify code of Tiny Tiny RSS 1.8.0 (PHP-based) to highlight words that have been matched by filters using regex expressions

Hello Freelancers, We are looking for someone to create a plug-in or modify the code of Tiny Tiny RSS 1.8.0 (PHP-based) to highlight the words that have been matched by the filters using the regex expressions. The preferred route for this would be a plug-in so as TTRSS is updated we do not need to re-update the new code, and if something changes in the source code that effects the highlighting we know to change it in the plug-in source code rather than several files within the TTRSS source… Attached is a document that has screen shots of what we are trying to achieve. I believe this functionality can be achieved by replacing the matched pieces of the expression and replacing the same text with a highlight code added wrapped around the matched word. (like a background color). I am sure there are many different methods and that is up to you! Please indicate if your bid is to change the source code or to create a plug-in to give us this functionality. Thank you.
