Do Gtk programs on Windows or Mac have the same, non native file selector dialog? I mostly use Linux (Ubuntu with i3wm) for coding and what annoys me most on daily basis are the file pickers on different applications. They are not only inconsistent, they are also all bad compared to Windows and Mac. It takes me far more time to select files than on the other platforms. Granted I use it mostly by far when webbrowsing as I use the commandline mostly but still at least a few times per day. I cannot check if Win or Mac Gtk apps use the platform picker or a Gtk one: if the latter, that would stop me from deploying software in Gtk on other platforms.
