Idk, but the app itself is bad, that I can confirm. No directory structures, wth google? Especially because the old, beautiful design still exists, it's sometimes used as a file chooser, it's just not available as a standalone app. Well, FX is better anyway.
Oh, I never noticed that, thank you!
But I must say, featuring some buttons as seemingly shortcuts to the real directories but only providing a real structure further down without any shortcuts still seems like a weird design choice. In the end it's the same workflow as e.g. FX, except requiring the user to scroll to the bottom every time, which is an action that takes a lot more time than a simple click.
