Are mobile native apps "idiomatic" then? Speaking of uis made with native frameworks of a specific platform. They surely share some patterns, especially on navigation, top bar, button bar, etc but it's been the death of design and ux. You can't use any app with one hand alone, everything is flat. I share the sentiment that some basic elements should behave the same, like inputs, but I miss the day where we experimented with uis, especially with early internet and flash. Sure many of these looked bad and were horrible to use, but in some ways each one had some character. We basically stopped doing any ui innovation on both the web and native desktop/mobile platforms and that's sad to me
