Lifer Highlighter in Chrome with OffiDocs
Lifer Highlighter Chrome web store extension
DESCRIPTION:
Run the Chrome online web store extension Lifer Highlighter using OffiDocs Chromium online.
Highlights lifers on eBird's website by suppressing ones you've seen with a muted gray color. Very basic.
Input your life list in the options textarea (you can download your list from "My eBird"). Once done pages loaded on eBird will cause birds you have seen before to show as gray rather than blue. This way you can pick out the birds you have not seen before easily. You can now customize the colors.
