We so far have been recreating the background elements for all the item throughout the shell. This merge request simplifies this by unifying these elements into a single component, making is easier to keep things at a consistent design while also being able to adjust things when needed in the future.
Per request, I tried to keep thing looking mostly the same as before.
The first picture is what the action drawer looks like now, the one after is with these changes.


Implementation of a popup button to rotate the screen while using gesture navigation.
The button is set to appear when the device rotates while auto rotation is off. Then the button will be visible for a short period of time before disappearing.
