For posterity, I’ve decided to make a list of all the features browsers have that should be mimicked in all those other browsers. Keep in mind that some have duplicates, just so I didn’t have to add additional ‘combination’ entries. Anything missing would be welcome.
- IE8: Hideable menu bar, Web Slices, Accelerators, Tab Isolation, Compatibility View, Offline Mode
- Firefox: Extensions, Offline Mode
- Chrome: ‘Application’ interface, Full-Themed (no native title bar), Start Page, Tab Isolation,
- Safari: Document Inspector
- Opera: Mouse Gestures
