Built an ingredient highlighter to help with allergies

So, one of my friends has pretty particular allergies, and doing their shopping online seemed like a hassle. They are essentially doing a Ctrl+F on every single product they come across, but they sometimes miss items since ingredients are often referred to by technical names.

I thought it could be a fun project to develop a "smart" version of this as well. I wrote a Chrome extension named AllergoSafe, which marks the ingredients and their entire set of synonyms automatically the moment it loads the page.

I've got it up and running for a couple of folks, but I was curious to see if anyone else was finding it useful. I'm looking for some feedback regarding the interface or perhaps some ingredients that could be included.

It's completely free. No accounts of any sort necessary. Just something I am attempting to optimize.

Well, let me know what you think.
