UI improvements

1. Move the "Back" to the top, put it into the same line as stepper:
   < | Step 1 -- Step 2 -- Step 3
< | Details -- Style -- Create
   It would make the navigation more fluent, as I don't need to look for the "Back" button. Plus, it would save some space. Clicking on either step should navigate to this step, otherwise it makes no sense. This behaviour would eliminate the "Back" and "Continue" buttons, however the "Continue" button can be placed at the bottom of the step (you put settings and click "Next", without "scrolling" to the top of the screen).
   
   Also, do you really need this button? Why not rely on Android's back button?
   Also, it might be a good idea to put this settings at the bottom, so you can use "one-handed" mode. I think these steps and buttons in there have more "click" than "Library", "Create" and "Settings". Have to be confirmed with other testers\users.
2. Give a better naming for "Custom". Right now it's not really clear what is custom.
   
3. I'm not sure there's a need for "Preview" \ "Pause preview" buttons. The title can be changed to "Journey preview" and the button can be inline media-control (when you click on the image\video, it toggles the play\payse state).
   1. No need for extra button
   2. Controls are fluent and recognizeble
   This is an example of how control can be embedded, but you only need "play\pause" button.
4. Also, the preview uses the resolution I selected: 2160p, which makes the preview a bit slow / freeze. I think, for the preview itself it can use lower resolution.

P.S. This is the Google Store version. It works the same as a manual APK download in terms of speed, look and feel.

the preview play control is now inside the preview in v3.0.4.

The look and feel is great now. It feels like a mature application. Thank you a lot!
