Feature request: support more back/forward gestures and keyboard shortcuts

I’m trying to make my mouse buttons 4 and 5 work as back and forward buttons respectively, which on macOS involves picking one of three things to simulate:

1. Three finger swipe left and right. The produces ideal behavior in native apps, but sometimes doesn’t work in non-native apps. At least some Logitech mouses take this approach. More info here: https://sensible-side-buttons.archagon.net.
2. Command-Left and Command-Right. Seems to be most broadly supported, but targets the focused window rather than the one under the cursor.
3. Command-[ and Command-]. Not as broadly supported as the arrow key shortcuts, sometimes used for different functionality like code editor indentation, targets the focused window rather than the one under the cursor, and generates some unwanted menu bar flashing.

Currently 1Password supports only #3, and it’s the only app on my computer to do so. Safari, Chrome, Firefox, and even some Electron apps support all three. I’d ideally want 1Password to support all three, too, but just adding #2 would be a much appreciated upgrade that I’d guess would be easier to implement. The way it is now I just don’t get to use my mouse buttons 4 and 5 in 1Password, because rebinding them to work with 1Password would break more than it fixes.
