Inserts info popups about airport identifiers found on web pages
Aviation enthusiasts, this one's for you.
This highly user-configurable extension finds 4-character airport identifiers (like KJFK, CYYZ, EGLL, etc) on webpages and inserts information about their location and distance from you.
With the settings pane, you can choose between inline information and hovertext. The link inserted is also customizable with colors (pick one or have it blend with the page) and location - you can even provide a custom link using the available formatting.
