FavIdenticon for Google Docs

Gives Docs, Sheets, and Slides unique favicons per document. If you have a bunch of Docs, Sheets, and Slides open in your tabs, the tabs can get so small that you can no longer see the document titles; just generic Docs, Sheets, and Slides icons. This extension gives each Docs, Sheets, and Slides document a unique favicon to make them visually distinguishable in a long row of small tabs. Over time you'll learn the icons for your favorite docs.
