The first one was started before the latest merges that introduce UI changes. Some of these things might already be added like the bottom navigation bar, but with a slightly different layout. The other ones were made a few weeks ago using the previous one with updated components, but not layout. Ignore the stuff that doesn't apply any more due to that time difference.
Feel free to leave feedback if you want, since it can definitely be improved.
Hey could you come up with a design with the screenshots? they're very hard to implement and wouldn't be as good as these ones
