Hi there,
I can develop this as an userscript (used with Greasemonkey/Tapermonkey). Would write it in JavaScript and it would take about 1 - 1.5h from award.
If you were ready to spend a few bucks more I'd be ready to code a browser plugin, but the userscript will do the task just as fine so I guess it's fine.
Milestone to be created as soon as awarded, but released once you have the working script.
Regards,
Julijan
