> Discoverability? Who needs it?

Most "flat" designed modern apps fail miserably at discovery. Most hide things in hamburger menus or require weird random swipes in odd directions with zero visual indicators.

I got bit by this recently. Brave on android has no "forward button in the app menu, it only has back. Chrome has both forward and back in the menu. Both browsers support swiping from the right side to go forward in the history stack (although this seems to be overloaded with switching tabs in a tab group), which I discovered by accident. What's odd about this though is that the device has a global back button that is also used for backward history navigation, but that's been duplicated in brave with an additional back action in the menu, but the forward history navigation is entirely hidden and has only one way to invoke it: via swiping.
