ReTab for Safari

Cmd+E to jump between the most recent tabs, Cmd+G to cycle through recent tabs history, Cmd+Shift+G to cycle backwards, and Close Tab also jumps to the most recent tab (toggleable).
ReTab is simple & light, which means it uses minimum memory and won't crash - sounds basic, right? But we found other similar plugins for Safari don't even meet these! We tried the others, but one doesn't work with the latest macOS, and the other causes several crashes every day - we contacted the developer who couldn't figure out the cause, thus decided to make ReTab by ourselves, for ourselves. We love it and hope you do too!
Why Cmd+E & Cmd+G as the default keyboard shortcuts? They're easy to hit with your left hand, and most other keys are already taken. Plus, Cmd+E is rarely used for disk ejection or “Use Selection to Find,” and Cmd+G is for "Find Again" so we think they're the perfect choices.
Want it on iPad too? ReTab is the only available extension for iOS & iPadOS (because others don't use the latest tech), and it's bundled together with the macOS version :]
