Small view: Assets screen and sorting

[Sergei-Beam]

moved from #56

1. Main screen
   Need to add:
   Show All button for assets

• If there are only 3 or fewer assets, hide Show all icon
• Beam should be placed on top of assets

2. Assets screen https://zpl.io/bl3EnNk
   Assets screen is opening via clicking on the "Show all" icon near the assets
   After opening by default all assets are sorted by "Recently used"

Sorting https://zpl.io/bl3EnNk
Need to add sorting icon which calls after clicking the sorting list
All sorting actions should be added from the list above

The screen was done without sorting cause I don't understand how the sort should work and what field it should be based on.
